Actually the human body can be said to be amazing because it has the potential to do things that might seem impossible. for example a viral video shows how a man can ride a motorcycle on the bus alone. The man does this by placing the motorbike on his head and then slowly climbing the stairs to the roof of the bus. It is estimated that it holds a motorbike load of around 137 kilograms. One thing is clear that heavy motor loads are supported by the neck of the man. This can only be done if the bones and muscles are trained. According to researchers from Cape Peninsula University of Technology the habit of lifting weights on the head may not be a good thing. Experiments on 24 women found that lifting items on the head spent more or less the same energy as other methods such as shouldering. Even lifting weights on the head makes the risk of neck injury increase. Some women even reported that they had to be massaged because their necks were in pain after lifting things. All women in the study agreed that they preferred other transportation methods to carry important items such as firewood or water.
