How violent are you?

In a fun, consensual way of course...

I play Rollerderby and last weekend took part in an outdoor event. As such, I saw many people, in protective gear, getting knocked down onto tarmac, bounce, thud or slide, jump up laughing and crash back into someone else. And this included various dainty 50yo+ women, not just dumb young men as might otherwise be assumed if you don't know the culture of the sport.

Meanwhile I have a social circle where the very idea of any physical contact past a hug is basically an anathema. I once jokingly bopped someone on the arm after a number of warnings and it did not go down well...

So I was wondering what other people's personal norms are in this area.
