Just wondering - do you girls and guy's do something called 'Airsoft'?
It was invented in the US a couple of decades ago, I believe and if you have a fourteen or fifteen year old son - it's been a good way to get at least some of the tension out of them...
Half of the time I don't like it very much - freezing (UK version is about +5C and wet) cold and wet and idiots propell gorified plastic pellets at you at up to four hundred feet per second. But sometimes, with the bonding , it seems quite fun!
Cold, muddy, but it is a test of fitness - half of the game area is a 45 degree slope and wooded. Try charging up and down that for about six hours
BTW, there is a girl who has taken part in the airsoft matches here. Just as tough or idiotic as the blokes...
