I don't place different value on "life". So my answer is YES! I would try to save, elderly, kids, animals etc.... If I knew it was feasible. I wouldn't try to be a hero.
To only try to save people you love says a lot about character. I despise my ex's but would still try to save them, cept the one who almost gave me aids.
I would however not save a human who has little value in life like a pedophile, child/animal abusers etc. To me, they are not life.
