This brings up something I'm grumping internally about. I've almost never worn a cup - not in soccer, and not in MA. I've been hit a very few times (in each of the mentioned pursuits), but not enought to convince me to wear protection. But now I teach much more striking than my instructors did, and use sparring more. I - and my students - should wear that cup. I just can't seem to get comfortable with it, especially when grappling.
I think I'm getting old and grumpy. I'm going to drive 27,000 miles to hang out with @Xue Sheng and yell at the kids on his lawn.
You're in good company, Gerry, Bill Wallace never wore a cup either.
