Why? And what could be healthy about something as destructive as embracing death?
I like to be pragmatic. I know very well that I will most likely die in a few decades. That’s just how it looks to be at the moment. I do however strongly believe we and the generations that follow us should fight death and that we can win.
If we could live forever, than we couldn't have any children (our reproduction rate is exponential, but there's only one planet that can hold us all and it doesn't grow any larger).
Stretching this, there would be no real notion of parents or grandparents. And it would get pretty boring too.
As most of us here, you're probably too young.
Do you have children? Wait until you see your first toddler walking towards you while laughing.
I don't think that's a particularly useful or healthy attitude to have towards death, actually.
