My presentation is slightly morbid.
After the previous touching presentation
I hope mine will work, too.
I am going to tell you how to become immortal.
You will learn a lot: about sleep, health,
but also why you should have your e-mail address on your tombstone.
Anybody knows Ray Kurzweil here?
One, two, three, many people.
He is an amazing scientist who knows a lot about artificial intelligence.
He has interesting futuristic predictions.
Such as in fifty years artificial intelligence
will be equal to human brain.
It is interesting for us that in 2099
- I did not sleep much yesterday, so my presentation is rather simple -
in 2099 we will be able to read human
mind and upload it into a cloud.
It will no longer be called a cloud,
but a matrix after an old movie.
If we manage, then there is a good news
that humankind will become immortal.
The bad news for us here is that we will not live to see that.
But I have a plan how we might manage,
and become immortal.
But we must work hard
and improve our health.
There is one thing that could help us.
It is using technology and measuring.
Let's start with sleep. I like that a lot.
Sleep is a wonderful thing.
Or, lack of sleep is a terrible thing.
Try not to sleep for one day.
What will happen?
Your productivity, cognitive abilities, motivation - all fall down to zero.
Laboratory rats survived 14 days without sleep.
Sleep fatally influences our health and inner organs.
Mainstream studies claim that unless we sleep 6-8 hours daily,
our life might be notably shorter.
Or, people who sleep more or fewer hours live shorter.
That is why we should deal with sleep.
Sleep is easy to measure.
It is done in sleep laboratories.
One uses PSG there - polysomnograph.
It is a sophisticated machine with several sensors.
The outcome of it is a hypnogram.
To be able to significantly improve
sleep one would need to measure it daily.
Not everyone though could have a polysomnograph at home.
And not everyone enjoys sleeping with electrodes on their face.
An alternative to that is sleep actigraphy
measuring sleep with the help of accelerometer.
How does it work?
Sleep goes through several phases.
Deep sleep is where we dream.
Our body needs to inhibit us completely.
Otherwise we would run around our bedroom, jump on partner's head,
fall off our bed.
Our muscles are thus totally inhibited.
We can't, however, spend the whole night like this,
because we would get up like from a coffin,
have bedsores and our blood would not have enough oxygen.
Body then needs to lead us from the deep sleep out.
In a healthy sleep thus the deep and the light phase alternate.
We made use of that and created one of the first mobile applications
which manage to measure sleep: Sleep as Android.
Does anyone use it here?
Great! Two per cent, more!
The application has already helped more than eight million people with sleep.
How does it work?
You do not need any other equipment.
Just put your smart phone beside your bed
and with the help of an accelerometer,
it measures as you toss and roll over the bed,
and you get an actigraph - similar to those from a sleep laboratory.
The first day of using the application can already bring improvements of sleep.
It does not wake you up at 8 am as common alarm clocks do.
It finds an optimal moment, the best sleep phase
in light sleep where it is pleasant.
You thus wake up as you woke up during weekend without an alarm clock.
A superb feeling.
If you are a parent, you know you always need to put kids to bed.
But there is no one left to put you in bed.
That is where Sleep as Android comes into play,
and when you should go into bed,
since we all work too long hours till night,
the application tells you to go to bed.
It also makes you get up in the morning, as the clock keeps ringing
as long as you do not complete a simple task.
Such as an arithmetical problem.
Users hated that one, so we changed it into counting sheep.
Or, if you are a keep sleeper,
you must go and scan a QR code above a sink
to stop the clock from ringing.
That gets everyone out of bed for sure.
It is crucial not only because we need a healthy regular sleep.
But also to avoid various sleep disorders
such as insomnia or hypersomnia - chronic sleep or sleeplessness.
Snoring is another issue.
We are able to measure it.
If you snore, the application can even chomp at you.
No need for your partner to do it -
Sleep as Android will do it instead.
There might be other consequences, other breathing difficulties.
These might not be as simple as snoring, such as obstructive sleep apnea.
The application can help you find out about any potential problem.
In the morning you will be able to hear the sounds you made at night.
At best, it will only be the other sounds.
With this application you can experience statistic orgies.
With every sleep, you can add info such as, "I jogged, worked late."
You can then find out t hat two beers before sleep
might prolong snoring by an hour.
Or, when you drink coffee, you sleep an hour less.
All these are aspects that might dramatically improve your sleep.
Today we collect sleep data from users worldwide - anonymously, of course.
Our database comprises today more than a million of sleep records,
which is a large number, more than any conventional studies.
We try to find out a lot about sleep.
We started by studying differences in sleep among countries -
where do people snore more, where they sleep longer.
But we would like to know the influence of caffeine, alcohol, sport on sleep, too.
Now you have seen how to improve your health thanks to sleep.
And also to prolong life, if you observe sleep hygiene.
But there are other issues, such as food intake.
Today there are plenty of medical studies stating
optimal food composition, daily dose of vitamins, minerals, and others.
If someone could supervise us,
couch us,
like an assistant, who would oversee us and prevented us from carcinoma -
that would be awesome.
Another issue is physical activity.
It dramatically influences sleep.
There are studies claiming one should walk at least 3 kilometers per day
to lower heart attack risk by 50%.
I have read an interesting study:
people who have hundred orgasms per year
prolong their lives by up to eight years.
Now we are getting closer to Kurzweil finally.
When I put all of that together,
I got to my new concept.
It is not perfect marketing-wise,
you might help me with a better name for it.
I call it DeathWatch.
Smart watch that does not tell you the time
but rather when you die.
It is a terrific thing.
It could be a great breakthrough
in how we all neglect our health
and do not manage to force ourselves into living a healthy life.
This thing could make us change.
If you also consider that 80 % of all death causes
are cancer or various cardiovascular diseases,
things often brought about by bad life style,
then such DeathWatch,
if we focused it on those 80%
could cause a dramatic rise in life expectancy.
So much that we may live up to the year 2099
and become thus in fact immortal.
If you were wondering, why I had my email on the tombstone,
it is because I hope that once that monument is built,
my body will be decaying somewhere in the ground,
but you will still be able to send me emails into matrix at petr@nalevka.com
including questions regarding this talk.
However, I hope this presentation will save your life,
and that you will thus become immortal.
And if it by any chance does not work out, then rest in peace.
Thank you.
