@rezoanulvibes hello dear friend. You are very right, life is beautiful and we also have only one, it is not a renewable resource, you have to be grateful and take care of it.

In matters of defense, everything is valid and allowed, you do not mention it, but a little dirt in the eyes of the attacker is a good option, or biting the ear is another thing that works.

Thank you very much for letting us know all these ways to defend ourselves.
I wish you a great day
