1) Knee.
2) Lower back.
(Do I get any change?)
come on Coyoteman, thats ridiculous, some conjoured up no evidence junk as that? the knee and the lower back? Let me ask you this, how come the knee is designed for forward motion and that exactly where are eyes are directed, or the toes. why arent they on the back of the foot? How come the human hand has five fingers inwhich it is the most perfect of design for picking things up and even the length of each finger or that the arms are directed torward the front and that the hands are placed with the palms to the inside inwhich each hand accomodates to the inside in effeiciency how come the mouth is facing forward and just happens to produce sound for talking tasting and eating all these functions that are accomodated by being directed to the forward position! etc...etc...etc...etc...etc...etc...etc...etc... The knee and the lower back as an idea of a bad design? Pure junk science hypothesis!!!!!
Do you Goose step.
