I fired my dad's Mauser 98 (it had been a war trophy that he had rebarrelled to an '06) when I was 12. I was impressed with the kick. It didn't knock me on my fourth point of contact, however.
Some time ago, there was a controversy at the DUmp about having a young child watch her parents having sex. I'd be interested in seeing where the bird-punching stoned primitive came down on that.
