Wolff's law

For thousands of years it has been excepted in Martial Arts that conditioning your body (hitting solid objects in this case) over time causes your bones, joints and muscles to grow harder, denser and stronger. I'm sure you've all seen MA films with people hitting walls, kicking tress etc. It's nice to find that science approved the idea and called it 'Law'.

Wolff's law is a theory developed by the German Anatomist/Surgeon Julius Wolff (1835-1902) in the 19th century that states that bone in a healthy person or animal will adapt to the loads it is placed under. If loading on a particular bone increases, the bone will remodel itself over time to become stronger to resist that sort of loading. The opposite is also true. (Davis' Law explains how soft tissue remolds itself according to imposed demands).

I have found that true science can co-exist if not re-enforce cultural beliefs/knowledge/religion. I think it's unnecessary one side to see the other as an enemy. May be we shouldn't think of something that hasn't been proved as wrong. A kind of innocent 'till proven guilty philosophy. It's good to see more co-operation happening in general between ancient knowledge and modern science and more acceptance that each can learn from the other.

Result from Woff's law!
