You wouldn't be conscious of anything, so it wouldn't be anything. Not cool. Just nothing. Forever. Only as long as you're here do you have options and chances.
We'll all be dead eventually. You'll have plenty of eons spent in that state. This is the only time we have to be alive. Heart beating, brainwaves firing, eyes seeing, body moving, hearing, smelling, tasting, thinking, learning... we are amazing beings.
Sorry if this isn't what you want to hear, or if I don't understand (because I honestly don't). But dying is NOT cool, Fornever. It's the exact opposite of cool. Nobody wants to see you do that.
