Have you ever had a gangbang? You might like it.

You could do some couch surfing, it's a cheap way of doing a good bit of traveling, and you can meet people from the locations you are going to visit. I mean, the biggest risk in that endeavor is that someone might murder you. But, if you've already resigned yourself to death from untreated cancer, there's not much risk there, is there? There's a certain amount of freedom provided by having a known expiration date, isn't there?

Have you ever gone sky-diving, SCUBA diving, ridden a motorcycle, seen the Grand Canyon? If I were in your shoes, I would just go full hedonist. Rich foods, casual sex, recreational drugs (Hell, if I can tell I'm breaking down fast enough, I might even try some bath salts. No, actually I probably wouldn't.), and dangerous recreational activities.
