>>some people are just not afraid of death. i dare say most of those who are not afraid do believe either in god or in some sort of afterlife. has nothing whatsoever to do with catholicism per se or any particular religion for that matter though.<<
If that's so, I'd be willing to be that nine of ten times, that person is either elderly (and has come to peace with the concept), psychologically/neurologically unhealthy or being dishonest. Fear of death is an evolutionary adaptation; avoiding death is a good way to not die and thus to ensure the survival of the species.
Most of the deeply religious people who claim to not fear to death are full of themselves. If people really, earnestly believe there is an afterlife of literally endless peace, love, and happiness, every religious person would want to die. This life would be a crap hole in comparison to that life.
In fact, religion's sole purpose is to hide from death BECAUSE we all fear it. We fear the unknown, and death is a huge unknown. Inventing fairytales that make dying awesome is a perfect way to conceal serious anxiety about it, and it is comforting to think that the loved one that just passed away isn't gone forever.
And, frankly, Mister Kitten, you may not have a hypochondriac's attitude about death, but if someone had a loaded gun to your head, don't tell me you would'nt be sweating profusely.
