Breifly define wolf Law?
Wolf law is basically a law that states that bone size and shape are greatly influenced by ammount of stress and force you put on the bones .
The high stress you put on the bone- the stonger your bones will be
the less stress you put on your bones- the weaker and short they will be

describe the davis law
- some people are just born with variations betwwen joints due to herditdity
Ligaments, muscle, and other soft tissue when placed under appropriate tension will adapt over time by lengthening; conversely, when maintained in a loose or shorted state over a period of time, they will gradually shorten
