David, I'd drop you and Chuck like two bad habits
So cool you are working as an Official. Wow.
I grew up boxing since my father boxed in HS and fought for West Point. Nothing serious on my end but it shaped a lot of my opinions about sport and conditioning. There is nothing so tiring as a three minute round.
I started boxing again last year in what we call "Slow Pitch Boxing". After a hip and great PT and CBO's I got back into a form of shape and found the right gym...guys around my age that wear pillows on our fists and head gear and have a hoot.
I so admire the UFC fighters, both sexes (sorry).
Alone.
