Take the immortal words of Freddie Mercury "Who wants to live forever?" I for one don't.
As an infant, the concept of living forever was very appealing to me, but as I grew up I realised that I really didn't grasp what forever actually meant. Infinity, you see, is, well, infinite. I could spend an eternity in heaven individually investigating the minutest detail of every atom within the entire universe, and yet still have time to do it all again, again and again and well you get the point. People often tell me that there will always be new things to discover in heaven, an infinity of new things! Oh goody, so now I have an infinity to discover an infinity of new things.
I attribute meaning to my life by realising that it is the one life I have. It is finite and therfore I have to make it best I can make it. How can I get that same meaning from a life that has no end?
