You are making assumptions in bad faith here.
You won't give anyone anything and no one will beg you for anything.
It is just going to happen at some point because people want to live (yes, even suicidal people, mostly) and not need reading glasses and worry about cancers and heart attacks by the time their kids enter high school.
I am not kidding myself that anyone currently alive will live to benefit from it, but I am also not kidding myself that I am or should be OK with the current status quo and that there is something romantic or beautiful about it, or that it is how things should be.
