a challenge?

I am a person who enjoys a challenge, within reason.  I like to win at card games and mental challenges, but I've never been big on physical games.  A glaring lack of coordination contributes to that fact.  So today, one week after hip surgery, when I'm still using a walker to go farther than across the room, I was not as inspired as I should have been by the morning news report about a 103 year old woman who just won two gold medals in her age group in running.  She did the 100 yard dash in 50 seconds.  I'm not sure I could ever do that.  So I refuse to consider running races when I'm 103.  I even refuse to consider being 103.
