Of course there will be no webbed cheeks, don't worry!
So what about swimming for a long time?
The first is physical. Just exercise and keep regular exercise is naturally good for your health. Swimming is different from other land sports, because the resistance in water is much greater than that in air, so the amount of exercise in swimming is much greater than that in other sports, and it is also beneficial to lose weight.
In addition, swimming is a whole-body exercise, which requires the coordination of the body, and it is easier to feel the details of the movement of the body in the water.
After all, people are not aquatic animals, so swimming needs to hold your breath and take a breath, which is very helpful to enhance your heart strength and vital capacity. People who swim for a long time will have a strong heart and a high vital capacity.
With one more survival skill, everyone can walk and run, but not everyone can swim. Especially in the north where landlubbers gather.
People who swim for a long time will also have some confidence that people who can't swim don't have! That's my confidence in the face of water. When I can't swim, I never thought about going to a place with water to try the depth. But after I can swim, I have the impulse to try the depth whether by boat or in an artificial lake. Fortunately, I am a very rational person, because I know that there is a world of difference between stagnant water and open water in a swimming pool! So although I really want to, but I didn't actually take action, there is a wise saying that I used to remind myself when I was impulsive, and I can also give it to you who can swim and have the urge to try:
Drowning people can swim! Don't worry about disaster, I mean the kind I asked for.
