I'm not talking death of course, they just wound up as vacant shadows. I dunno if there was something underlying in each case, but the eagerness people have to upend their brains is a little befuddling to me. You have no idea what effect they'll have on you yourself until you're too far gone to do anything about it. I don't believe it's something to be trifled with myself.
