As a research student, I spend most of my time working on my research career, even when I am at home, I am awake until 3 or 4 A.M just doing my research-chores.
As a matter of fact, long-term having not enough sleep, putting myself under huge amount of stress and hard work and more important, not getting enough exercise will directly put the person's health in to danger.
My question here is
how should a researcher balance his life to both maintain his health and do his academic job?
I am wondering whether professionals and scientists really hardly worked this much and how their healthy and balanced academic/work life-style is.
