I started c25k yesterday as well and am two years older than you. It's a great decision to not waste your life away being unhealthy and depressed and all of that; I completely agree.

I'm doing c25k on Thursday's, Saturday's, and Monday's; Friday's and Tuesday's I plan on doing other aerobic exercises at home (which usually get followed up by dancing around for another hour or two). I actually got out yesterday morning at 7:20 and it felt great. Don't get me wrong, it was certainly tough and I was trudging along in my jogging in the end, but my energy multiplied after that. I did more exercises today and have just been floating along in this exercise high for the entire day.

Have you checked out any 5k's in your area yet for when the time comes, TakingRoots?

I started running (with the C25k) when I was 37 and it began my love with running.  I wish wish wish that I had found this program when I was 22!  I was always fascinated with runners but never thought that I could do it.  I stopped running a few years back because of back problems, but never found another exercise that motivated me.  So now, I'm starting over and hoping that my back allows me to do this.
