Anyone feel like this when biking or doing aerobics?

I know this may sound a little silly, but when I mountain bike or do any type of exercise where I really put all of myself into it I start to feel like a kid. It's like I feel really good but kind of feel like how I used to when I was younger. I've heard many people say that people are addicted to exercise because it helps them to get away from their problems. Does anyone else get like this? I know endorphins are released, but it's kinda more then just feeling good lol. Kinda like a mild high. I dunno, maybe it's just my mind going through teenage hormonal changes lol!
