My legacy. What I left behind and what lasting mark I made on this world. Whether it be through my children (when I have them), whatever I did for work, my image in the eyes of my family and peers etc. That is what I would care about most on top of the obvious making sure my funeral and will was set in stone just how I wanted it. I'd also be looking forward to finding out if there is and what is the afterlife. I've always somehow looked forward to death to find out that question. Either I die and become and inanimate object with no thought process, pure nothing for eternity. Or there is an afterlife and its bad ass filled with everything I could ever want. Plus I get could the answers to all the unanswerable questions in life, like where the universe came from.
