People say how lucky it is to be a god.
But gods...gods can never die naturally.
Imagine never being able to truly love anyone because you either spend an eternity looking at them or you spend what is relatively no time at all.
Some people say that an eternity proves what is true love. But they don't understand that eternity is literally forever.
No matter who you love, unless you are a perfect being, you'll be bored of them after an eternity.
And that's why humans can not live forever. We'll become bored of it.
