This is why I only fight senior citizens.
I fight kids, then I can show off my kicks to the head!
When I get into altercations it's as the person who has to stop them, I can't go into them with the thought I might 'lose', I have to win if that's the right word, at any rate I have to prevail over the people who are breaking the law. I can do that by various means, not necessarily through violence and I'm not alone which is a bonus obviously!
Fighting competitively is fun and I think a great many fighters, certainly a lot of the ones I know aren't out to prove in the first instance that they are the best fighter on the day though that is very satisfying, the main thing is to prove to yourself you can do it. I think it's a useful thing to do to have at least one full contact fight in the ring/cage whatever to prove to yourself that you can keep your head, act calmly while the adrenaline is flowing and can think what you are doing while fighting. Not quite the same as being attacked but close enough for you to reassure yourself you can have a damn good go at defending yourself. If you win it's cool but if you don't you'll still be pleased with yourself so as they say it's a win/win situation. Whats amazing perhaps is the bond you form with the person you've fought, you end up grinning at each other and going off for a pint!
