A couple weekends ago I was at this rock formation in the Bay Area called "Castle Rock". Castle Rock is a sandstone rock formation that has an excellent scenic view. There were lots of young people on Castle Rock practicing technical rock climbing. Castle Rock is just sufficiently difficult to climb that it's a little bit spicy. Now I'm a 23 year old guy trapped in a 47 year old body. My immediate reaction was: "It would be fun to climb that." I actually got up to go climb it when I thought: What's the probability of killing myself turning my wife into a widow and leaving my 1 year old daughter and 4 year old son without a daddy. In my mind I balanced the satisfaction of climbing that rock against the downside risk of killing myself. Upon reflection, I opted to sit down and play "peak-a-boo" with my daughter.
