People have a distorted sense of the meaning of the words "young" and "old."
Young people are whining that they're "old" when they turn 25.
Professional cyclists, hockey players, football players, basketball players, boxers -- many of the best are between 25 and 35. Which athletes do you see being judged "too old" by 25? only gymnasts and figure skaters. Look at Didier Cuche -- 37 and still beating the younger guys on the ski hills.
I thought I was old when I turned 20.
If I use old or young on this forum I mean relatively old or young. Professional athletes are definitely not old in the geriatric sense.
