I doubt we would agree on what being in good condition actually means. I can tell you that it is a moving target, based on age, and at 63, I am not the same as at 53, or 43, or 33, or hell, if I were 23 and felt like this, I would have probably hanged myself.
When my knees started getting bad, about 6 years ago, I started riding my bike every day, weather permitting. Most days, I do between 4-6 miles around the neighborhood. When I started, I could do 5 miles in about 25-30 minutes. Now its about 40. Does that mean my physical condition is worse? Knees are, that's for sure.
tbone, you have come up with the perfect "Trump" defense. Don't pay any attention to Bil's words, its whats in his heart that matters.
