Out of shape at Western Michigan University

Just got back from visiting Western Michigan University.  Next Spring will be the 10th year since I graduated. And here is one thing I learned from a day of walking campus:  I AM WAY OUT OF SHAPE.

I used to walk all over campus, every day, all day. No problem. My wife and I (we met there), were in bad shape after 2 hours. Just tired and achy.

Ironically, next Sunday we're playing paint ball with friends (both my wife and I). That's for 4 hours. If walking at a leisurely pace on campus made us tired in 2 hours, we're doomed next weekend!
