The bottom line on aging and running performance is this: we do not know our limits. The real barrier seems to be the mind, not the body. According to most experts, our true life span is 100-plus years, and whether we make it has much to do with our attitudes, beliefs, and lifestyles. Our bodies are simply waiting for our minds to give them permission to go beyond what most of us think is the finish line.Running Within
This is my favorite quote because of the comment on, "our true life span is 100-plus years".
Based on another book I read I like to tell people that when I turn 100 I will ride 100 miles!
And of course our attitudes, beliefs, and lifestyles has a lot to do with if we get there or not.
I would like to thank TriFrog for recommending this read!
