Isnt that funny how it works? In the 80s, in my racewalking days in California, i was up to 30-40 miles per week. Then one day at RW class, as a warmup i just started jogging on the track, and did a mile! Easier than i did when i was in 9th grade! Why did i let that go???

By trying not to have regrets, you have OTHER regrets! They dont tell you that. "Opportunity costs." Thats what they need to teach in high school. Forget GNP & GDP carp!
