You'll get used to 6 or less hours of sleep per day.
Plenty of time to sleep later in life.
Truth. Sleep is for the weak. I will sleep when I'm dead.
hahahaha...it's not about that really..
You lose some -quality- of life for your later life, if you do not sleep well during your younger years.
The reason is.. While you're young, your replication system is working well.
But the derioration is NON-linear..
which means if your system is not in good order before you hit the point of hormone disregulation. Late life will become quite an agony, diabetus, heart disease, internal organ failures, muscle wasting..
There's been numerous studies done comparing muscle mass of people who exercised during their peak years vs those who just lounged around.
The result is, the people who exercised retain 75-80% of their muscle mass @ age 80. while the people who never bothered to build those muscles had significant wasting.
