Low blows. Why are they bad?

[Kev]

Thanks, cool video and how ironic Abner Mares was the guy doing the experiment!

It answered some questions but not really though. I can understand how a shot to the balls could be clearly awful but how many low blows actually hit the balls thoguh? 1 in 5? It seems to me that most 'low Blows' are just below the belt line but still well above that area, I mean the belt line seems to be at the belly button whereas most peoples balls are a good 8 inches or so below that I'd imagine, yet fighters routinely throw themselves to the ground when they get hit on at hip level or even slightly above.

To Agbeko's credit though, he didn't complain at all during the fight and just kept working. Judah by contrast was a complete bitch.
