One may argue that the denialist approach to mortality is even worse for mental health.
Not everyone wants to live forever. My grandparents lived to their 80's. My father, who is a bit over 60, considers that to be a very reasonable number, and I feel the same way. I don't want to still be here in 60+ years straining the resources of my daughter's generation.
Death is not a failure of the design. It's an integral part of it.
And that's Stockholm syndrome at its maximum expression.
