Once you're no longer competing in sports (or even if you never did), are you still an athlete? This inclusive definition of the term has potential.
But in my twenties I found some forms of exercise I didn't hate, and in my thirties I started using the word “athlete” to describe myself. It's weird to.
On occasion, athletes collapse. This can occur in the midst of competition, during practice, or at the completion of long endurance races.
