Sleeping less than 2 hours a night for a long period of time may make you live less.
Same with diet. Eat a normal average diet, and you're set. Eat MacDonalds every day for breakfast, and maybe you'll die a bit earlier.
Don't forget also:
total happiness = time spent doing something * happiness level
eg, I would hate to maximize for 'time' at the expense of average happiness level.
The chances are we'll mostly die from accidents, cancer, etc anyway.
Show some evidence. I don't buy it.
Also, if you're looking for some data, the problem is that many fatal accidents' causes are reported as unknown. Given the results of the simulation, a majority of those accidents may be related to sleep deprivation.
Sleep deprivation is dangerous. But it's also obvious. You don't need to read a book to know that.
Researches have been conducted which proved that the condition after a lack of sleep 1 hour each night during a week would be equal to the condition when you haven't slept through the night.
