Is it Wisdom or Just Old Age?

When I was a young man (not that I'm all that incredibly old now in my mid 30's), I would take chances that I wouldn't even dream about taking now. I would jump off cliffs into the local lake. I would make things open by hitting them with my hands. I would even fling myself off of the roof of my house into the shallow end of my pool. I wouldn't even dream about it nowadays. Is that wisdom telling me that it's not a good choice? I believe it is just my aching body.

I have found over the past ten years or so that I do not heal as quickly as I used to heal. I once sprained an ankle pretty bad (swelled like a grapefruit and was completely black and blue). I was walking on the damned thing two days later and moving around normally within a week. I stub my toe now, and it aches for three days. About a year and a half ago, I tore open a muscle in my shoulder just throwing a ball to some kids. I went to three months of physical therapy and decided against surgery. My arm still aches from time to time depending on how I use it.

I have come to the realization that I am not wiser. I would still do all the crazy crap that I used to do if I trusted my body to heal quickly. I haven't stopped because of wisdom. I just stopped because my body can't handle it.
