43 I had completed an ironman and played soccer 3 times a week for about 7 years.
As a kid I was so skinny (6 ft but only 135 lbs). I was in band and art. I had a summer bday and graduated before I was 18. I grew up in a family that didn't do sports and I was embarrassingly bad at sports.
Now I love playing soccer / football / skiing / rugby etc and take special joy in being significantly better than all the athletes who I was totally jealous of but peaked in high school.
