@spaf Meh. How many people do you know, famous, and known to be living in memory as you say, on account of kindness? Clearly this is a shallow ruse by some sentimental cartoonist ;-).
Immortality (in the sense of being remembered) is far more likely Hitler's reward than it is your outrageously kind granny's the memory of whom will disappear in a generation or two or three ... 5 or 6 tops. How many people trace their line further back than that and notably on the basis of "kindness" ... if they do, it will be on the basis of church records typically, deaths, births, marriages, and be stuck mostly with the paternal line (as anyone who's tried some genealogical research knows).
So, Happy 2024, but don't under any circumstances live forever, move on when your time comes, and lay the seeds while you live (with kindness) for a better world and life for your progeny (if any) or those of your community (if you forgo having any of your own).
