Why bother with anything, just live and die when it's your time. Don't waste valuable ground space by being buried, be cremated and have your ash spread around a garden or somewhere you enjoyed being during your life.

Yes, it does. It means exactly that. I hope you've started.

Nope. You will be just as dead whether you are in a pine box, in a pyramid or just decaying on the ground and will not be aware of any of it. Now, don't concern yourself about your demise as it will happen when it happens. Life is brief and unpredictable so be yourself, go out and enjoy your life while you still have the privilege and opportunity to do so.
