I know so many people that are scared of death. Who like to pretend like it couldn't happen to them (that's a folly of most youth) or want to live forever through medical science or be cryopreserved to be revived when medical science catches up to whatever they die from.
But I don't know if I'd go so far as to say "death-denying". When people die, their families and friends morn. Most don't pretend like it's not a big deal.
Sorry, I should have been more specific, but I kinda got lazy with this question.
Basically, some argue that our society is so afraid and anxious because they realize that they are in fact going to die that they deny death in order to make themselves feel better. Some argue they do this by religion (determinism, eternal life) and also by trying to stay young (which is all over the media of course- skin creams, make-up, hair dye,fashion and especially plastic surgery- voluntarism).
But then again others argue that we as a society are accepting of death. We embrace it in a way by preparing for it. Wills to take care of our family and our burial done by lawyers, religion, health and medicine (assisted suicide, making death painless, etc).
Not sure that Americans deny death so much as try to sugar-coat it and not face it head-on. I also think our funerary traditions are kind of senseless, like embalming and spending money on luxury coffins.
