Facing Problems While Installing Java
This question came to mind while watching an overloaded vehicle tilting down the road ahead of me. Are Kryptonians Height &amp; Weight Proportional (H/W/P) to humans? I'm curious to know if Clark has to fly (hover just a little bit) in order to adjust his weight and level load a cars suspension system so he blends in when he travels with earthlings in automobiles.
