In a fictional sense it a really good trope. And its a great way of developing conflict for the characters involved. In a realistic sense its stupid because I feel like for most if us we would put the few over the many. I mean if we use the last of us example. If one our close family members...
It's sucks for me as a brit because we use this weird hybrid of both for example I would say that character was 6ft tall and weighs 600 kilos. He ran at 400 mph whilst drinking 3 liters of water.
