We've heard of three men who shielded girlfriends with their bodies and, ultimately, their lives. These are only the ones we hear about, simply because they died. How many other men (including husbands, by the way) did the same thing but are unsung, simply because they lived?
And, how many women attempted to shield male companions the same way? I think we know the answer there. I'm not putting women down...I'm pointing out that there are some things that are just wired into (most) men genetically, and crisis brings it to the fore. Just as I'm sure there was plenty of male heroics on the Concordia--it just wasn't PC to report it.
