I'm fortunate that, by and large, I don't really get stressed. I adopt a very 'what's the worst that can happen' attitude (with work mainly), though my missus can put me through the wringer with the rest of life sometimes. If I had peoples lives in my hands, or I had no family willing to support me, I could see why work would stress people out. But ultimately it usually comes down to something unimportant being a bit late, or someone not making quite as much money as they should, or some other immaterial bullshit that I shouldn't be stressing about in any shape or form.
Riding my bike also helps, and video games, and learning something new (should always be learning something, IMO, fantastic way to occupy the mind).
