Why do people fight with their hands down

[Red Sun]

And unless your anatomy is a little off, there's nothing all that vital in your butt anyway. Sure, it hurts, but it won't harm you when you get kicked in the butt.

But what if the strike glances off the butt and hits you in the coccyx? :/

It hurts, but is extremely unlikely to harm you in any significant way.

For takedown defense.

Absolutely...

If you look at historic pictures of pugilists the early ones have a much lower guard. As the rules changed and throws, grabs and takedowns were removed.. The guard become higher.

 

[Kung Fu Wang]

To have your

- right hand in front of your right knee, and
- left hand in front of your left knee,

is the best defense against single leg and double legs.
