Would this be a result of the anti-stress effects - biochemical - of exercising?

Looks like it enhances release of the neurotrophic BDNF which in turn does result in new neurons! Only we'd need to exercise
a lot to replenish - ha
The Effects of Exercise on the Brain
Exercise is a stressor too, but a good sort of stress. What interests me is that the pituitary gland gets cued to release endorphins a "feel good" chemical that helps your system to smoothly return to homeostasis.
Can anyone think of another "good stress"? These would be other things that should elicit same release of endorphins. Funny thing is I thought "landing a good job", "getting married or @your wedding" though for me these in the end were stressors each one bringing with it its own sort of angst. Can anyone else relate? I couldn't even fully savor accepting a good job offer. Instead, I went straight to worrying. For me there is only stress and really bad stress.
Why does good stress result in release of BDNF?
Also wondering did any of you ever have a bruxism (teeth grinding)prior to diagnosis? Funny thing is the doctor asked about any new stress in my life, I responded with a negative - How do you respond when you don't even recognize it in yourself. It is chronic and low level like your limbic system is always idling, but it feels normal, and you assume that this is how other people feel. Does this sound familiar to anyone?
