i started when i was 21 with back problems. so at 24 its no problem. tell us where you are and maybe someone can suggest something. personally, i think it would be better to find i good school and go there rahter the choose a style no matter how good the school is. well, "how can you tell if a school is good?'. go to as many schools as you can to see how they train. ask questions (depending on the sifu, they might get touchy if you ask to many). if you want sparring ask if they do. a good sifu typically is very humble. he will say something like " come try my class. if you like it you can join. " try and avoid things like "my style/school is the best" stuff like that. after you find some places and are still iffy about them, post their website here and someone might help. also as a beginer, dont get fustrated or intimidated by the more advanced students. everyone had to start sometime. good luck. and about ther master thing. after a little while, you wont even think about it. there is so much to learn. the more i learn the more i know how little it is.
A BJJ player and notorious pimp, Da Big Deezy, in the Crenshaw district tried to "raise up" and "slap a ho" ..... I impaled him with my retractible naginata. I wish there were more groundfighters in the world. They make my arsenal that much more deadly. - john takeshi
