Sorry to hear about losing your father, it's certainly hard to fathom. My dad lost his at a young age as well.

I would give my life (or anything else) for my son or anyone else in my family or group of friends. No questions, no hesitation.

Some of us live our lives that way. Would rather give my life for someone I care for, than live knowing that I didn't try to save theirs.

Edit: I live my life with no regrets. Sometimes things work out, sometimes they don't. A decision was made given the information available at the moment.
