Can you teach me how to do that :-)
Honestly, I think there is something to it.
This one was easy: when using a flashlight & needing two hands, I'd put it in my mouth (usually boat-related & no headlamp). I'd be likely gag but decided that couldn't happen. A blend or "battle" of psychology &/vs. physiology? (things within reason anyway:)
I am having pain w/ some postures where I had hernia surgery last 8/23. When I think about it, it bothers me considerably more than when I don't.
Yes, my neck/arm bothers me a lot more running than orienteering - too much else to think about. But hamstring cramping ...
