And yet that stupidly high sunk cost is exactly WHY people should be walking away from it! It may seem silly to the person involved to walk away from something they've invested so much in, but it's actually the right decision. It's like consistently losing at cards but you keep putting your savings in anyway, hopeful that you're on the right track and you'll pull through, but entirely aware that you won't have a house, savings or a wife at the end of the game! Of course, you have to be pragmatic enough to even contemplate this concept, which most of these happily vaxxed-and-dying people are not. Hence we have people treading the paths they're treading. But you and I already know this, PolarNinja ;-)
