Col. Anthony Biddle, USMC

[Devildoc]

The man, he was a stud: joined the Marines at 41, developed hand-to-hand and bayonet training, and was a for-real boxing champ.

I'm not even in my mid 30's yet and there are days my body aches, let alone joining at 41 and whooping 18 year old asses through age 56.
