You guys are not well-trained athletes. Nice try.
I run 15-20 miles/week, and my VO2 max is in the Top 10% of men my age. So I am certainly not a professional athlete, but I am definitely in far better shape than most hamplanets in their late 30s (that was solely for
@dodint)
I've been in the 40s for a while now. It was actually cool looking at the last two years when I really picked up my running, watching my RHR rate fall through the 50s to where it is now.
I look at the heart like a car. The more miles you put on it every day, the faster it is going to break down. The way I look at it, my heart is not working as hard so it should last longer.
