Man is symmetrical, in that his right side is a mirror image of his left side. I think women are symmetrical also. <img src="eek.gif" border="0"> In fact, all mammals are symmetrical. All birds, fish and insects are symmetrical. The only exception being crabs and tennis players, which have bigger right arms. <img src="smile.gif" border="0">
Man's inventions are founded in nature. The car, the boat, the plane are all symmetrical. The lowly bicycle and tricycle are even symmetrical.
Why was the helicopter made asymmetrical? <img src="confused.gif" border="0">
