Common sense based on what? That implies some general consensus. It's your own opinion and it's been disproven by the fact that active people do suffer with bad stress. Your thread is nonsense mate.
What do you even mean? You're literally saying "stress is good if you're active because it motivates you". Probably the most naive and ridiculous statement I've ever heard. I'm active and I've suffered from bad stress. So what exactly is your point? What is the point of this thread?
Stress is awful. I've suffered from bad stress and anxiety. It's a horrible feeling. Also it has nothing to do with being active/inactive. I've played sports all my life, I go the gym, and I coach tennis. Conclusion: don't listen to OP
