My sons are short guys but they prove the adage, "It's not the size of the dog in the fight that counts, it's the size of the fight in the dog!"The shorter guys I've known felt forced to be tough. First to get aggressive, but also the first to defend their friends. Big guys relied on size, but the littler guys knew how to scrap. That changed, though, if the guys were in martial arts. One of the guys I did kung fu with was smaller than me, and year over year, his scrappitude went calm. If you're ever in danger at night, pray for a calm short dude to show up.
Why yes, I do know kung fu. Also yes, the tits and ass have thrown off my balance a bit.
