Boxing is actually a subtle power confrontation until the opponent is knocked down, so the players who really play the game will go all out.
Boxing is particularly harmful to the brain at first, because even if you wear a helmet when boxing, your opponent's strength is particularly great and the damage is great. If it is serious, it may cause dementia. Traumatic brain injury is a common disease of many retired boxers. This disease will produce a new symptom of Parkinson's disease, which will lead to a certain decline in players' memory and cognitive ability.
Boxing can also hurt your eyes. For example, Zou Shiming, who was shot in the eye in many competitions, always endured the pain to finish the whole competition. Soon after, he suddenly went blind, saying that the visual nerve was damaged and the possibility of cure was very small. In severe cases, it can lead to blindness.
In fact, the boxer really deserves our respect because he won the gold medal for us with his blood and tears. However, after they retire, there will be many physical problems, which is actually very inconvenient for their later life. So we really don't want to make up these people who have worked hard for the country to hurt them, because they have worked hard enough. Why can't we give them more tolerance?
