Because people are going to die after all. As workers at the bottom, all our hard work and efforts in this life are not to create value, or to put it bluntly, just to earn more money to survive. How many people are exhausted at work for one or two hundred yuan a day? How many people can't go home and earn more overtime? How many people give up treatment because they can't afford it, and lie in a cold place in the hospital forever? Think about it. The poor and the rich must have different ideas. 5 million is a piece of cake for some people. For example, some celebrities can spend millions on plastic surgery and splurge on consumption. If you change their life span by one year, it won't work, not even for a month.
Even if I can have hundreds of millions of net worth in the future, no amount of money can be counted as myself. At that time, I still hoped that I would choose like this. At that time, it may be of little value to yourself to exchange a year's life for 5 million yuan, but for many people, it is enough to have a better life, be able to afford books and be able to afford illness. I hope that I will have such a realm in the future.
Of course, this is just a hypothesis. Everyone will measure the easy choice with a very rational attitude. When they really face such a situation, it is hard to say, because we are all human beings and have human weaknesses.
