They say that not getting sleep leads to all kinds of problems.  That it causes your body to hold on to fat because of a spike in cortisol.  That it leads to decreased cognitive function.  That it weakens your immune system.  That it can increase stress because the body isn’t able to repair itself and the brain isn’t able to process data.

Can’t I just sleep when I’m dead?
