I appreciate the offer. For me there's no great mystery; I die every night, and wake up every morning with that dead guy's memories. Life takes effort, and keeping that cycle going just hasn't been worth the effort for a long time. I made the decision months ago.
I think there are a lot of people who keep putting in the effort only to avoid imposing suffering on their loved ones and others. So, in a way I'm lucky in my loneliness: I'm free to be selfish.
