| Pretty much agree with what has been said so far:
For martial arts? Yes. For fights? No.
However, if one did want to be able to use these things in fights as a way of being evasive you would have to train in these techniques so much that it becomes second nature to do some kind of acrobatic trick instead of simply blocking or taking a step back.
Also... getting bit by a radioactive/genetically modified spider while on a school field trip would help quite a bit. |
