It is definitely required to train and learn Hosinsul to neutralize the enemies so we can ensure safety from them.

There are various occasions you can imagine. For example, a molester confronts a walking woman at night, a co-worker gives you trouble at the office, and somebody catches you from behind. Hosinsul really works at any kind of dangerous confrontations. It is so useful whether you are attacked by a drunken passenger in the subway or you are travelling in a strange town. It is also good for the old living alone.
