Jogging - Running

Well, I've been jogging now for three weeks (about). I've jogged and such before, but didn't like it much unless it was a social time. Now, I'm actually liking it. I'm not sure why. I do like how I feel afterwards - tired, a wee bit buzzed, feeling like I accomplished something. I'm only up to three miles at this point, but am really thinking I may stick with it for now since I really enjoy it. I also thought this poster was funny.
