You sir, are an idgit.
The man is a tremendous athlete. Age doesn't matter if he is still running fast then so-be-it. Who cares if he is 50 years old, if he's able to get 3rd place then there it is, 3rd place.
You are putting too much emphasis on a number when it doesn't matter. Younger athletes need to step on the gas if they are within 3rd place and Meb is near.
