How to Save a Life

Why do people risk their own lives to save others and why do some people look out for themselves first? Well, I think people save other peoples' lives and risk their own because they think it is the right action to do and it is a good deed. It could make the person feel better about themselves knowing that they saved a person's life when they could have lost theirs while doing it. I think some people look out for themselves first because they are selfish and want to make sure that they are okay and not care if other people are dying or injured. Or that they are too cowardly to risk their life, where they would like to help save people, but again are a little selfish and don't want to risk their life being taking if they do help.
