And in fact I find that "viewpoint" totally incomprehensible. I can asure you, I loved my mother much, much before cancer killed her at 52. That was not a gift, that was her body malfunctioning and our ignorance about how to fix it.
I have no need for death or grief to love or to value life, thank you very much.
And I don't keep my mouth shut about this because I worry about the real consequences of that philosophy. At any other moment of human history acceptance of death was perhaps the only sane thing to do, because there was no alternative. But we have now a scientific civilization and we should be fighting it, instead of rationalizing it.
