Once you reach a certain age, you are very much cognizant of people you know dying... and while death is not a very pleasant subject about which to talk, it is nonetheless something that happens to all of us at some point in time during our lifetimes...
Some of us believe in an afterlife and that afterlife is going to take place in this marvelous place called heaven while others believe that when you are dead you are dead and there is nothing else that happens to you outside of decaying in your coffin.
Whoever created us, gave us anywhere from 80 to 100 years of life in a world of eternity. So why just live 100 years... why not live 500 years or 1000 years... especially since there is no end to life in general?
and, while we are on that subject of life, why do we think that we are the only lifeforms in the universe... with all the billions of galaxies and solar systems, there has got to be other forms of life... otherwise what was the frigging point of creating the universe?
So death is rather confusing in that we may not really die at all... we may just leave one body and go into another body somewhere else in the universe... or we may float into space and become part of cosmic consciousness.
But since death is inevitable, I cannot imagine why so many people encourage it with alcohol consumption, illegal drugs, smoking, and engaging in dangerous hobbies... death is going to come soon enough so why encourage it?
