Who played professional sports and does not miss playing after looking back on a career?
I can think of nearly no one.
You miss the adversity because that is what bound the relationships so tightly together.
This is the same way that soldiers form relationships and miss their comrades.
Maybe they just miss their youth.
“I miss being twenty-five years old and playing with my friends,” said Plank. “Now we’re scattered across the country and it’s all in the past. If you’re lucky enough to experience something that intense when you’re young, you pay for it the rest of your life.”
