I could be totally wrong, but didn't bio mechanics lead to "position golf"?
I think if it has been mis-applied it leads to 'position golf.' But from my understanding bio-mechanics is basically the study of how the body can move and its range of motions. For instance, I'm right handed...play golf right handed, but I'm left eye dominant. Because of this, in order for me to 'see the ball' I keep my head down a bit longer through the swing. I'm not thinking 'keep your head down', I'm just trying to see the ball which is a pretty natural instinct. Probably not the best example, but that's sort of what I get from understanding bio-mechanics.
