I'm a fencer. Mainly Foil but I will do some Sabre and Epee. It's
tons of fun. Like Greg700 said, there's not many sports that can compare to the exillarating feeling of fighting a duel. It combines strategy and the mind with much physical movement. Nothing could be better! It's a great stress relief as well... I get to stab people without facing any consequences... BaHaHaHaHaHaHa! (*insert evil laugh here*)
Everyone is welcome to fence. I know kids that can kick my butt from the professional coaching they have recieved. And I heard that the women who holds the record for the world's oldest person started fencing at 80! Anyone can do it! It's not hard to find a club, and everyone is open and friendly to everyone else.
