I learned Sanda in the summer vacation. I went to about 600+ a few years ago.
In fact, learning only provides a means of exercise and teaches you some basic routines by the way.
But it is particularly effective for strengthening physical fitness. After a holiday, you will find that your physical strength is much better.
Better go together. There is no need to learn to fight with a man who supervises each other. There is nothing to be afraid of if you want to fight hard.
I'm 93, too. So I hope I can help you give points.
