Your story has an extra dimension - Bravery. Some people will just jump on the grenade, run into a burning house etc. It's an instinct baked into some small part of the population. No thinking involved. Helping others day to day doesn't always require bravery (physical strength/low fear of physical danger) or courage (mental/moral strength). Situations where its required (as with the lifeguard) training definitely helps.
