Going very slowly is a step in the right direction safety wise, but even then, I think it's a bad idea to mess around with it. As you noted, O Sensei broke somebody's hip. That's not an injury you heal with a band-aid.
There are other systems that have already made a study of those things you are looking into; you should look into one of them instead of trying to dope it out by yourself, again, because even going slowly, it's just plain safer.
You do first of all realise that the human body is not made of porcelain and that O sensei knew what he was doing right?
The possibility of me, a relative novice being able to hurt someone in that way with a simple punch is astronomical, even if I put everything I have into the punch I would probably just end up hurting myself.
Please, when you respond to a thread in future, take into consideration that I might actually be an intelligent adult human being. Your response, while well meaning was rather patronizing.
