Three guys in my gym THIS YEAR alone have stuffed up their fists by hitting things/ people without gloves on. Takes months to recover!

I won't say it can't work but I think I'd hurt my hand because I'd need 100 % perfect skills and a bit of luck to not hurt myself hitting someone.

I'm just beginning to learn a bit of Judo. I think if I had to I'd end up using a combination of things as fast and as hard as possible and then just running.

I like to think that anyway. I wonder if I'd be ready for it when it happened in an unfamiar situation - would I react instantly the way I might if i was sparring? I don't know!
