There are many that I've read who stated they would be bored if they had eternal life. However the life we live is very short. Those with great fortitude may live to 100 but that quality of life is not that great. I take care of the elderly and watch them die. Those that lived a long life by human standard look at death as a relief because of pain. But too often these elderly ones comment how fast life went by. I think so many of us both Atheist and Theist would be more accepting of death if our life wasn't so short. To think that on average the earth will revolve around our sun maybe 80 times then we die.
So many never truly live. But I must agree with Dawkins how we has individuals won the biological lottery. Our chances of even existing was so remote. And to complain about dying is very selfish.
