Also if you sleep well, and live 25% longer, that 25% will be when you're old, senile, and unable to do anything useful.

Studies about sleep are often just crazy. When did people stop using their common sense? Just have as much sleep as you think works for you.

Has every old person you've ever met been old, senile, and unable to do anything useful?

My Grandma walked to the supermarket the morning of the night she passed and was totally lucid for the entirety of her years.

I'm sorry to hear that your grandmother passed. How did her startup take the loss?

[perfTerm]

Hahaha I don't usually laugh at jokes about Grandma's passing but that got a good chuckle out of me.

That's assuming you do become senile and unable to do anything useful. Doesn't necessarily have to happen, and that doesn't mean you shouldn't live a good life.

What's considered "common sense" can vary greatly from person to person, and people aren't always aware of how their habits can have long-term negative consequences on them.

[nicboobees]

Habits like reading every scientific paper and worrying about them?

[artmageddon]

No, habits like only getting ~4hrs sleep or oversleeping regularly.

Or perhaps the point where you become "old, senile and unable to do anything useful" will also happen later?
