your own death that is...
it will happen eventually

For myself to answer the question, it doesn't really bother me, especially when you think about those other small creatures in the world who only get a 1 year to live.
so yeah, Not scared of death my self, I just think it will be like a never-ending dream you enter when you die, brain working or not, your soul will enter a dream like world. I'm not a relijous guy either.
however, what I am scared of is losing family and friends, that's the worst thing of all.
