What is the experience of falling on the highway?

It must be very painful to fall down in high-speed skiing. Anyone who studies chemistry is bound to fall down. Especially when I fell down in high-speed skiing, no one wanted this feeling and experience. To try and experience. I fell down because I was too fast. It really hurts.

But it is really normal to fall down in order to learn skiing, and it is also a difficulty that we have to face in learning skiing.
