On the other hand ...
At my "home" YMCA at the beginning of this year, they announced the "1000-Mile Cardio Club," which is a deal whereby you pay in $20 and turn in, each day, the "mile equivalent" of that day's exercise activity, be it running, treadmill, elliptical, spinning class, swimming, etc. If you've turned in a cumulative total of at least 1000 miles by year's end, you get a fabulous prize package that includes a water bottle, a "regular" T-shirt, and a "dri-wicking T-shirt." I'm not clear on what that last thing is, exactly, but it sounds cool, so I know I must need one. The guy who's running this thing sends out a weekly email with a spreadsheet attached, in which you can see how you're doing against schedule (as it turns out, I've built up a 45-mile "cushion" already -- aren't I good!). He also tracks average cumulative miles per person by age group. Guess what the results show?
Age 50 - 59: 98.45 mi/person (I have 127.5!)
Age 40 - 49: 75.12 mi/person
Age 60 - 69: 70.69 mi/person
Age 30 - 39: 70.10 mi/person
Age 20 - 29: 61.92 mi/person
Age 19 and under: 50.40 mi/person
Hmmmmm ... see a trend here? Maybe there is a little something to be said for people my age, after all. Now, if we'd just start dressing decently when we go out in public ...
