i agree with Andymcc. it's not a huge part of the curriculum. as for deformed hands, it depends what you call deformed
. a bent finger or two for me doesn't constitute deformed. and that is even hard to do unless you want to break with your fingertips. i don't think anyone here is advocating the breaking of 12 blocks of concrete with the hands or anything. but if you do everything correctly, breaking less than 8 wooden boards or so won't leave you permanently scarred.
