I've noticed...

This is just an observation. Ive been going out for to a few bars for the past couple of months. Yes I do come home late and miss out on sleep. But Ive started to notice something. I'm the type of guy who loves to dance. Especially when a good tune comes on. Id even dance by myself. The thing is, whenever I come back home from a bar after going wild on the dance floor, I get this feeling of energy and happiness. Its like my body feels rejuvenated. Even the air smells better and this is no word of a lie. Its not like I feel euphoric or anything .But its a cool feeling. So my guess is that all that dancing must have the same effect as exercising. It has to be endorphins being released during 'exercise'. Its a really good feeling. And from this maybe I should try and eat right and start exercising again. But this here's the problem: I can dance all night for 3 hours and feel great, but if I over exercise for over 20 minutes I then start getting exercise induced asthma which I find really weird. So why is that? And how do I sort that out?. I'm going to have to start taking responsibility for my mind body and soul and start doing some research!
