In fact, whether a person uses his left hand or his right hand is a matter of personal habit. In basketball, many stars are actually left-handed, but when they play, they all throw with their right hands. For example, James is used to shooting with his right hand when playing ball, but in daily life, James is left-handed. Moreover, James himself has revealed that he is actually left-handed, and it can be seen from some photos he signed for fans that James is a real left-handed.
Generally speaking, when a person is used to using which hand at ordinary times, he will subconsciously use that hand in everything, while James uses his right hand when playing ball games, but his left hand in daily life. That's because of human influence. James grew up watching Hardaway and Jordan play ball. They all shoot with their right hands and are very accurate.
It is also because of their influence that James thinks it is good to shoot with his right hand. Later, when he was learning basketball, his coach told him that as a player, he should not rely on only one hand, but should switch freely with both hands. James remembered the coach's words and did it. Moreover, in the NBA, there are many people in the same situation as James. They shoot with their right hands in competitions, but in daily life, they are left-handed.
