How can I put it? I will never do math problems when I am old, because I am not very good at math. Isn't it obvious that I want to get into trouble when I am old? When I get old, I may choose to play games, because it doesn't require any brain power, and I can get happiness from it. As for math problems, I really don't want to touch them. Math problems demand too much on people's IQ. After retirement, those who like to do math problems are either math teachers or scholars in math-related fields. Otherwise, who will retire and do math problems, will you? Certainly not, because math problems are painful memories of many people. How many people were scared by this math problem when they were young, but they still have to do it when they are old? Isn't that because they feel sorry for themselves?
There is a saying that although the math problem is difficult, it is very painful to do. But it is good to continue to do math problems when you are old, which is beneficial to prevent Alzheimer's disease, because Alzheimer's disease is caused by not using your brain much or aging your brain. Doing math problems can perfectly avoid this kind of problem, because doing math problems requires brains, and it takes a long time to understand, not the kind that can be solved by one brain. Of course, doing math problems every day doesn't mean you can't get Alzheimer's disease, because it is mainly related to age. But doing math problems every day can effectively prevent Alzheimer's disease, because you are exercising your brain. Of course, another thing is that you often do math problems, which can also ensure that your logical thinking is still clear when you are old.
Generally speaking, I can't continue to do math problems when I am old, because I don't like math problems myself. Doing math problems is a torment for me.
