How about Tom Brady played ALL of last season with an MCL injury?
I didn’t know that (I only follow the Seahawks) - but that’s what I mean, they tough it out. Of course it isn’t a mental thing that might be dangerous.
I wonder if any race car drivers have ever quit mid race because they weren’t quite at their top concentration level? Not sure I can see Richard Petty coming off the track on lap 12 and saying he needs to quit and practice mindfulness.
