Then you have all the thought-terminating cliches that float around such as "life has no meaning without death", "aging is beautiful", "aging is natural". Society is generally very pro-aging and consequently pro-death.
Of course, it's not a crazy attitude at all in our current world where aging is guaranteed. It's much easier to come to terms with something you know will happen for certain. People fear cancer far more than they do aging. The diseases of age are as brutal as they are numerous, and I can absolutely believe that dying is preferable to suffering in many cases. For thousands of years this has been the case, for thousands of years people have had to find ways to come to terms with it. Consequently this idea that aging is actually a good thing is embedded so deeply into our culture that it may as well be part of our DNA.
Why aren't we doing more about it? Why aren't billions being invested into research aiming to prevent/reverse aging? We outspend by a factor of at least 100x on treating the diseases caused by aging. We all know why: social pressures make it very difficult to advocate for without being seen as a naive fool scared of death reaching for immortality. The collective, pointless, preventable damage to humanity will continue to rage on.
