a) I noted it was heroic twice. He is the Man of the Hour.
b) That it also has severe consequences... which is a two edged sword... one side being that it is dangerous enough to be considered brave the other side of which is the cost of failure severe... that together it explains why heroes is a rarity... it tends to be something for the greater good which in turn limits the spread of such a nice set of genes... I don't think people get much of a time to think it through... so they either have trained for emergency situations and/or have the 'right stuff'.
c) I noted that it is different scenario for a parent with (young) children... mind you I think being a parent I would be now far more prone to do the same for a young child then an adult.
