I've got to weigh in on this subject. My mid-life crisis involved, but was not limited to, fulfilling some childhood dreams, one of which was ski patrol. Just by sheer coincidence, I met the local OEC instructor in line at the local donut shop. One thing led to another, I just followed the lead, took the course, passed the various tests (probably just barely) and found myself a ski patroller at age 52. Believe me, I had to ramp up the skiing abilities big time in a short time. I just finished my 2nd season as a vollie patroller and I state that my ski skills improved by orders of magnitude over the last 2 seasons. I'm 53 and of course I notice that my injuries take a little longer to heal, my top end is lower, perhaps, it might take me longer to get in shape for a running race, but I pay closer attention to my health and fitness, now that I have to work for it.
Utah, I saw that clip on the Today show. The fact that those guys could come back is very cool.
A friend of mine was about 80 lbs overweight, age 59, absolutely no physical fitness, did not have a sport in any season, ate crappy food. Well, he just took a hit and is lying in cardiac care with 10% of his cardiac function remaining. He will likely not ever leave the hospital unless he gets a transplant or artificial heart. Very sad.
