I was just thinking while watching the Zookeeper movie. If a child is born and we teach it how to move on it's legs and knuckles instead of just it's legs would it end up being a great deal stronger than people it's age? I think the most weight ever lifted by man was 450 KG, and an average gorilla male can life up to 2000 KG. Would this also have any negative impacts on the spine etc.?
