@GoshisDead,
It's the "worth living" thing that's confusing. When is a life not worth living?
We talk about quality of life. In my mind, if the drive to live is there, quality isn't an issue. When the life force recedes, it doesn't matter what the external circumstances are.
In other words, I think life itself is enough.
On the other hand, they say Kierkegaard died with a big smile on his face... like he'd figured something out.
