The question assumes you were once there – wherever there may be. 
I’m a hockey fan. Through the years I’ve watched countless NHL players battle injuries to get back into the lineup. Each year after one team lifts the Stanley Cup you then hear about all the off-season surgeries. Players sometimes play in every game of a playoff run with injuries that would prevent many of us from reporting to a desk job. Surgery is followed by extensive physical therapy to regain the strength necessary to be a successful professional athlete. 
Physically, I clearly can’t relate. Relating to being a professional athlete is impossible for me.
