Video summary
The speaker opens by recounting a critical incident from 2001 involving Canadian astronaut Chris Hadfield during his first spacewalk, an event that serves as a powerful metaphor for navigating challenges in aging and dementia care. Initially focused on the grandeur of space, Hadfield suddenly encountered condensation droplets inside his helmet that grew larger due to the lack of gravity, eventually clouding his vision and causing him to lose sight in one eye before going completely blind in the other. Despite the terrifying situation and the inability to perform instinctive actions like blinking or rubbing his eyes, Hadfield remained calm thanks to the emotional support of his crew member, Elena Chao, who kept him in a problem-solving mindset rather than letting panic take over. He realized he could complete his mission with his eyes closed, finished the necessary repairs, and was safely returned to the station, illustrating that success often comes from working through problems incrementally rather than waiting for a perfect solution.
This story transitions into a broader discussion about how space agencies approach chronic issues like social isolation and physical degradation, which are also significant risks for people aging on Earth. Astronauts experience rapid muscle loss and bone density depletion due to microgravity, requiring them to exercise for two to two and a half hours daily just to maintain their baseline health upon landing, often ending up in wheelchairs until they can rehabilitate. Similarly, social isolation is identified as the second highest risk factor for dementia, prompting space crews to implement simple yet effective solutions like communal meal times to foster connection and reduce depression. The speaker emphasizes that these are not high-tech fixes but fundamental shifts in mindset and system design, such as renaming medical garments to "maximum absorbency garments" to remove stigma, which demonstrates how language shapes opportunity and resilience.
The core message of the presentation is that we must adopt a proactive, solution-focused culture inspired by space science to address the rising global burden of dementia, rather than waiting for cures that are decades away. A recent global report highlights fourteen modifiable risk factors, including hearing loss, physical inactivity, and social isolation, which collectively account for nearly half of all dementia diagnoses if addressed. The speaker argues that aging is not a permanent decline but a condition that can be managed through the same systematic problem-solving techniques used by astronauts, where failures are viewed as data points for improvement rather than defeats. By integrating these lessons into our daily lives—correcting hearing loss, staying physically active, and maintaining social engagement—we can build resilience and significantly improve the quality of life for ourselves and our loved ones facing cognitive challenges.

Thank you. I take it you can hear me.
That's good. Good morning.
In a few moments, I'm going to tell you
a story that I hope opens up your
curiosity for some of the things that we
often don't notice when we're looking at
and admiring space science. I want to
tell you these stories because I think
that we need to be thinking differently,
thinking more long term and thinking
more constructively about what's ahead
for us and our loved ones. I'd like you
to be thinking about how this imply
applies to you as well as the people
around you and then talk about it more
because we certainly don't talk about it
enough.
I want to go back to 2001
when the Canadian astronaut Chris
Hadfield was on attempting his first
spacew walk.
This spacew walk is described along with
others as being kind of the dream that
astronauts have. And once they spend
more time on the space station, they
often call it their holiday or vacation
from the intricate and demanding life of
space station.
Chris had put an incredible amount of
effort into his preparations just like
any astronaut would.
He worked on or on sorry he worked on
the ground and in a pool learning the
intricate steps he would have to take in
order to make the repairs and
installations on the Canada Arm 1 which
was a essential piece of equipment for
building the space station.
He was partnered with Scott Perisinski.
They were going to go together to make
these repairs. He was supported by the
crew in the space station as well as the
ground crew on Earth.
This is such an intricate and important
time. If you like space, you probably
know that space is trying to kill you.
It's an area and space that we cannot
survive in. So, it requires a space suit
that at the time required three hours to
get in and prepare.
This space suit was designed for up to
eight hours of space walk or period in
space plus a couple of extra capsules of
oxygen just in case they needed it.
And Chris worked to make sure that this
was perfect. He made a joke about he was
so particular about it, he double shined
his helmet.
He gets into the spaceacuit and often as
described it's like a square peg and a
round hole. The space suit is not
designed to go through the portal and
take some time to get out, but he's
supported by his space crew to do so. He
gets out in space in under about an hour
of working through these pro this
assignment that he has, things start to
change.
He said he went from admiring the
amazing sense of space, bigness, and
humility to being really concerned about
what was going on inside his spaceacuit.
for him. He was looking for
sorry he suddenly realized he was
looking for or looking around and
spotting little droplets of water
wandering inside his helmet
and he was aware that this was not
supposed to be happening.
These micro droplets started to flood in
more and more and then because there's
no gravity started floating into each
other attaching and becoming larger
droplets. The larger droplets started to
float more slowly and one of them
attached to his left eye.
Now you can imagine that what would
happen here is that he would blink like
we would instinctively
but that didn't move the water or the
fluid.
He tried to shake it off, but without
gravity, it didn't move.
He even went to do the automatic thing
that you and I would do, is try to rub
his eye, but his space suit came up and
clunked against his helmet, only to find
that he did not have that option either.
As he was blinking, closing his eye,
trying to reopen it, closing his eye,
and trying to reopen it, he realized
that his vision was diminishing.
It was becoming cloudier and cloudier
until suddenly he couldn't see through
that eye and it snapped shut.
It's okay, he said. That's probably why
I have two eyes.
He started to work through the problem,
reported it to his space partner, his
crew, started talking about what was
what was going on and if he could remedy
the situation.
They also were talking about what would
happen if things got worse. How would
they get him back into the space
station?
Meanwhile, these droplets are not
stopping. They're continuing to float
inside his helmet,
becoming bigger and bigger. And of
course, latching to his right eye. He
does the same activities, tries to f
break it free, and nothing goes.
It's clamps shut. He opens his eye and
realizes he is completely blind.
Okay, he said that was definitely
unexpected.
we didn't train for this.
He reports this to his space partner. He
reports it to space crew and then he has
to say, "Houston, I have a problem."
He relays to his capsule commander,
Elena Choa, what's going on and how
things are. He's safe, but he's got a
problem and he's not exactly sure what
the remedy is. That's okay, Chris. We've
got you. She relays the situation to the
engineering teams, the biomedical teams,
the space true crew team to try and
figure out how to solve this problem.
Meanwhile, they're working on the
ground. She's translating to Chris
asking good questions about what's going
on. Meanwhile, the space crew is in the
space station trying to figure out how
they're going to get him back, get him
out of his suit, and figure out what the
issue is. Meanwhile, Chris is standing
still trying to figure out what's going
on. He's thinking about his options.
He's thinking about how he does not want
to finish that. He does not want to stop
this. He wants to complete the work
because he's representing Canada. This
means a lot to him. The purpose of this
mission is hugely important.
Elaine continues to talk to him in a
calm, emotionally
even voice. She is the emotional side of
his brain right now. She's making sure
that he doesn't move into fight or
flight and start to panic. that he
remains in problem solving mode because
the goal here is working the problem.
While everything is going back and
forth, Chris is continuing to think
about what's going on. And he's
realizing, wait a minute, I've done this
so many times, I could do it with my
eyes shut.
And so he decides and relays to his team
that he's going to continue with the
work. He's going to continue to do the
repairs and the installation, and he
thinks he can complete the mission.
They stand by his decision.
He finishes the assignment. He's
assisted back to the space station by
Scott. They remove his space suit inside
and they work to solve the problem.
These are the kinds of stories that I
tell families when I work with them when
they're diagnosed with dementia or
navigating it. Families who are caring
individuals who are navigating the
symptoms that they're experiencing.
I want them to hear that it's important
not to do things alone.
I want them to think about how they take
holidays, how they plan, how they have a
plan B, how they have teams they can
turn to, who are those teams, and to
call them out
because holidays getting out of our norm
are risky. Things happen. You might have
had things happen here in this trip
today, this week.
For people with dementia though, when
things happen, things are highly risky.
They can land people in hospital. They
can spoil ever taking a holiday again.
And that's not what we should be doing.
We should be building in systems so that
when we're challenged by chronic
persistent conditions, we do these
things successfully. We don't do them
alone.
But there this requires us to think
about how we work the problem. This is a
fundamental part of how the space
agencies think through things.
This particular phrase, work the
problem, was coined by Jean Fran CR, the
flight director of the Apollo 13
mission. He needed to get that crew back
and he couldn't afford for people to
say, "There's no perfect solution. We
don't know how we're going to do this."
He needed to work systematically through
all of the issues to keep his crew calm
on the ground, keep the crew in space
calm so that he could successfully get
them home. And this has carried on for
decades in the culture of the space
agencies in space science.
They are not going to wait for the
perfect solution to travel or live in
space.
What we are actively doing though is
working towards small incremental
improvements to keep us there for longer
so we can learn more, collect more data,
be informed about what's possible in the
future.
This is a really important thing to do
when lives are on the line. You can't
afford to seek a perfect solution and
not have a plan for the interim. You
can't write it off as if it's just not
worth the effort, right? And that
certainly doesn't help the ethos, the
culture, and the belief we have around
astronauts being heroes, space science
being fantastic, traveling to outside of
or off of Earth a dream.
This is a fundamental part of why
astronauts and the space agency need to
make sure that they keep the image of
traveling to space positive,
strength-based, and worth investing in.
But remember, it doesn't take big
solutions to make this happen. And a lot
of the things that are going on in space
are things that are happening in aging.
As we age from after the age of 30,
when we navigate how people do things in
space, we can learn how to do it better
on Earth. This is an opportunity for us
to think about what is ahead that we
haven't been told about because we don't
have enough role models
and how can we turn or change the
chapters that we've seen that haven't
gone well.
We also have more and more evidence
about how to do this well. There was
recently a global report released on how
to reduce our risk factors for dementia.
There are now 14 solid risk factors that
we can reduce that will improve our
ability to avoid it altogether.
The challenge is
that we often think it's genetic. We
often think that it's a one it just
takes a cure or a treatment. But the
challenge with cures and treatments is
they are at least a decade away. And
meanwhile, we need to be navigating
what's going on now. We need to be
working the problems
and NASA and other space agencies do
this really well. So one of the factors
around risk, one of the risk factors for
dementia is social isolation,
something that we've all been affected
by in the during the pandemic.
Social isolation is the second highest
risk factor for dementia.
It's also a risk factor for astronauts.
In fact, over the period of time
astronauts have kept journals, they've
recorded feeling isolated. And it became
such an issue that the ground crews
started to think, how are we going to
solve this? Because we can't have people
going to space and navigating de
depression. That is not going to work.
So they started thinking about what they
could do in really restricted
environments like the space station
where it's filled with equipment and
people and not a lot of space.
But it doesn't need to be high-tech.
Okay. So, what do they do? They want to
bring people together who are share who
are on shifts. They're often sleeping in
different time zones and they're not
exactly their workloads are so heavy
they don't have time to talk, but they
do have time to eat. So, what did they
do? They bolted down a table and in the
picture on the left brought astronauts
together from all over the world. so
that they could eat together, share
stories and connect and their journals
entries started to change. They were not
experiencing the isolation and they were
not experiencing the levels of
depression.
Small easy solution. They probably will
work to improve this, right? It's not
really a great environment for 12
astronauts to gather around this small
table. And as their eating improves,
they'll need to start thinking about
what that means in the future. But this
works. Now
the other another risk factor the third
in the list is physical activity.
When we don't take physical activity
into our older years, we experiencing
the same things that astronauts do.
Astronauts experience
[sighs]
muscle loss and bone density loss. In
gravity, there's nothing to push
against. And so the bone starts to
remmineralize into the body and the
muscles start to waste.
You might know this if you're a fan of
astronauts, but you might not. When they
land,
they cannot walk.
We don't know this because the image of
an astronaut walking isn't really great
for space.
But what you can tell is that they
actually end up being lifted out of the
space capsule, wrapped in blankets for
their medical checks, and then put in a
lounge chair.
A lounge chair, aka a wheelchair.
They're wheeled off into rehab and have
been for decades where they rehabilitate
their bodies and their brains because
they experience cognitive impairment,
too. but they're actively working to
make sure that they get back into the
body that they were in before they took
off for space.
We also know that physical activity is a
fundamental for space because of this
wastage.
But they have had to spend decades
developing new and improved exercises to
understand how to stay in space longer.
There's been five or six reiterations of
how to make this work because exercise
without gravity is virtually impossible.
Now they're cinched in, weighed down,
and they do two to two and a half hours
of exercise a day, six days a week, just
to maintain the strength and bone
density they left Earth with. They're
not even improving.
But they know when they get on land,
they can build that back up.
We don't talk about rebuilding,
rehab,
experiencing abilities to recover. We
often assume that this is a kind of
permanent state that we're living in as
we get older and that there's nothing
that can be done. But we can actually
learn a lot from what astronauts are
doing today.
There are a ton of parallel challenges
that people face in space and we will
space as we a as we and we will
experience as we age.
The challenge is that on earth we don't
use the same positive language. For
astronauts it's really important to keep
positive to keep that working the
problem idea to keep solution focused.
So, their wording is continent's
management systems when it comes to
taking care of how they poop and pee.
They've gone so far in language
that they have renamed the nappies they
wear for launches, return to Earth, and
spacew walks
to mags,
maximum absorbency garments.
Right? That's fancy. We don't often hear
the difference in the language, but it's
there and we should be adopting it
because then we can start to improve the
situations here.
We need to be thinking that the bone
density changes, the muscle adaptations
that astronauts are experiencing are the
same as the bone density loss, the
muscle wastage that we talk about in
age. We need to be thinking about how
the isolation that the astronauts are
focused on and fa and working to solve
are the same things that we need to
solve here for ourselves and our
families and the people who matter to
us.
It also means that we think differently
about different disrupted sleep wake
cycles like astronauts experience
instead of thinking about delirium and
wandering and worst case scenarios that
we might associate with dementia or
frailty.
When it comes to high stake
decision-making, astronauts turn to
their teams.
They don't assume that they just need to
be managed for the risk that they're
managing and play small.
This is my pitch for thinking
differently about it because I know when
families take these things into
consideration and put these things into
place, they live better. their dementia
symptoms drop, their frailty improves,
their experience of living with dementia
better for longer is present in our
communities.
They should be lessons that we take on
board for how to prevent it, how to
support and and care for our loved ones,
how to think differently about it rather
than to just focus on decline,
deterioration, and loss. That just
doesn't take us anywhere.
This world report that I show talked to
you about was presented or created by
the Lancet Commission. They did a global
report on the impact of dementia on the
world. They looked at population
studies. They looked at longevity
studies. And they highlighted these 14
really important
activities that we can intervene on to
reduce our risk of dementia. And when I
say dementia, I mean Alzheimer's
disease, too, because Alzheimer's is a
dementia. There's over 100 types of
dementia. I work with a dozen of them in
the community. We need to be thinking
differently about our cognitive health.
How to build resilience, how to do it
better, how to prevent it, and how to be
ready for cures and treatments when they
do arrive.
The fascinating part about this report
is that when they compiled all the
numbers, they said if we could reduce
all these risk factors, all 14 of them
around the world,
we would reduce dementia diagnosis
by 45%.
We should be thinking about this. This
should give us goosebumps. This is an
opportunity to change something that is
affecting the world over where we're
hinged on waiting for a cure or
treatment when there are things that we
can do today and it doesn't matter how
old we are.
It may be that only a few or half of
these apply to us.
But it's important to think about what
they are. And what's really great about
this particular report is that they talk
about it as a lifespan issue starting
from early years and how we're educated,
how we take that education through life
and continue to learn all the way
through our years.
How we look at how our social
engagement, our physical activity,
whether or not we can correct for
hearing loss and vision loss. By the
way, hearing loss is the number one risk
factor for depre for dementia if it's
not corrected.
It's a fundamental. And if you think
about it, these are all integrated and
interconnected. If we can't hear well,
we can't be socially engaged, which puts
us at risk of depression. Another risk
factor, which affects our heart health,
which is another risk factor, which can
create more isolation, which creates
more risk of not doing physical
activity, of gaining weight, obesity,
another risk factor.
This report is available to you. It's an
opportunity to change how we think.
Taking inspiration from astronauts means
that we have better language and a
better mindset and a better problem
solving technique than we have today. I
encourage you to think differently about
these. And if you're inspired by space
science like I am, this is your opening.
But it takes a moment to we have to
think differently. So I'll leave you
with this story.
This also is affected by our human ego.
We're proud. We're proud of what we do.
We're proud of who we are. And
astronauts are no different. Astronauts
come from highly competitive type A
personalities who have had to fight to
be at the very very top percentage of
everything from flight school to a
competing for astronaut spaces to
maintaining them.
But they also have to participate in
research and sometimes they get to they
need to get knocked down a little bit.
So a few years back they were
considering how do we manage continents
in space? This is a huge effort. It's
run by the human waste division and the
first director was called Dr. Flush.
Right? Because humor matters. So a team
of engineers devised this plan for
taking urine, capturing it, and then
returning it to space to be measured so
that they could anticipate needs for the
future. They called in a team of
astronauts. They explained the
situation. What they had devised was a
condom-like device that was attached to
a pipe using working as a catheter to
draw urine into a container that could
be returned to space safely.
The astron they told the astronauts they
needed to test it on Earth. But they had
devised three sizes for them,
asked them to choose one, return home,
test it, come back and give them
information about how well it was, how
successful it was, and what needed to be
improved. Sounds like a good thing to
do. Comfort of their own homes. The
challenge was no one took the size
small.
So they came back, reported that this
was a huge failure. There was urine
leakage all over the place. This wasn't
going to work in space. You can't have
droplets floating around in space
damaging million dollars of equipment.
They can't be floating around harmful to
astronauts wandering around. They had to
fix this. All
right, constructive feedback. Went back,
looked at the situation, realized that
actually this might not be their
problem.
Thought about it differently.
Took it back to the astronauts, renaming
the sizes.
You don't have to say much, right? You
don't have to confront the problem. You
just have to give them some insight
about how they're looking at things.
success in their research because they
thought differently because they were
working with humans who are a diverse,
not perfect,
but they needed a solution. So, they
worked the problem.
I encourage you to work the problem.
Laugh about it. It's funny. Aging is
funny. The work I do is hilarious.
But it's also incredibly important for
us to think about what's ahead because
we're living longer but not necessarily
better because we're not having the
schools and tools and skills to live
with live with it.
So here's some short pieces to take with
you. Remember you'll know problems are
data not defeats. You need support
systems. You need to build capacity and
capability into your systems.
Seek updates. Don't assume that what you
knew yesterday is all we need to know.
Work the problems.
Remember that language shapes
opportunity
and that preparation enhances
resilience.

you very much for your attention.
