I started an excercise program about 14 months ago. Membership at fitness center, personal trainer, the whole deal. I can do 50 pretty good push-ups now and feel great. Last week Traci (the trainer) suggested I let them do a series of tests to determine my physical age (compared to my chronological age). The clock says I’m 54 and I slid in at a cool 48. And, if I’m willing to live like Lance Armstrong, I can take that down to about 30. Call me skeptical. I think we’ll shoot for 45.
