Does a person walk with his left foot or his right foot first?

Usually on the left. Actually, I think it doesn't seem to matter which foot to move first! Say that your right foot is far from your heart, then take this step first, your heart seems to have no load! I think it's a matter of habit! Foreigners say that the right foot is far from the heart, and moving first is beneficial to the transmission of blood. I remembered an interesting discussion with a fortune teller. Fortune-teller said that every step a person takes will bring luck, whether he takes his left foot or his right foot first, luck is different. So it's luck to go out for a long trip. The author said that if so, in order to get good luck, people had better not walk, but jump with their feet together, so as to at least avoid the "bad luck" brought by taking the right foot or the left foot first. Another way is to stay where you are.
