Is it fashionable for the elderly to swim in winter?

This has nothing to do with fashion. This is personal resistance. Some people have better immunity, so they are more resistant to some things than others. Young people are afraid of cold because they are not used to washing cold water. I was scared at first, too, but if I wash it slowly and get used to it, I will be less afraid of the cold. Old people's winter swimming proves that they are healthier and have better resistance. People who often swim in winter can not only hone their will, but also exercise. Many elderly people like swimming in winter, which is one of the best ways to enhance their blood circulation and metabolism.
