I've done lots of different martial arts. and I suppose my reasons have been different for each one. Initially I started with Jiu Jitsu to learn self defence, now at that time I was at a very rough boys school and I used to get into lots of fights and the JJ was useless for them, after that I became a bit disillusioned with the whole idea of self defence.but later I started karate, then Aikido and just carried on changing styles as and when I felt like and I still do that now
..the focus in karate was fitness, in Aikido I just liked the look of it, very graceful and arty, Tai-Chi the same...............with Escrima because I was learning to use weapons I was very much focused on self defence.
One thing you realise after a time is that some folks , even the teachers have never had a fight in their lives, and have never actually ever used the stuff that they have learned.
so I've put other as well
