Utilize your body for retirement so that you can fit in to handle your other phases in life of chasing income at your depreciations of man-power to activeness.
So many people are too eager uncontrollably chasing after income without undermining their ages and so as considering the health fitness of themselves at ages.
if you're able to moderate what you're doing and how you go about combining your work and taking good care of yourself and your health, then over working wouldn't be a serious problem. Would you rather prefer to stress out now and get the needed things right or you would prefer to sleep while you should be working and hustle while all your mate have retired and are having the best of times with their grand children?
I believe their is time for everything and that's the reality. You have to hustle while you still have your strength and when the time comes you will have enough time to rest and play as much as you can.
It's only bad when youre just working without paying attention to your current health problems. You need to work, occasionally take some break, give yourself some sweet treatment and then cone back to re fire. That's how it goes. You literally rest in the grave so just get used to it.
