You can handle stress for productivity. In stressful times i managed to get so much done and felt better after it than every break could give me...

I think many people here confuse normal stress with depression, or desperation over situations...

People thrive when they want to achive something, even if it stresses them trhoughout the day, its about the fulfillment, that makes someone feel good... achieving a break feels much better than just taking one...

But yeah i think that boils down to having a healthy goal in live, for which you can stress out ...
