Yes, I think I would. First of all, I'm a planner, and I'd like to plan my funeral and the distribution of my assets. For example, I'd like to make provisions for Fluffy. Also, my vast collection of Conan The Barbarian, Savage Sword of Conan, and Conan Saga comics ought to go to a person who truly appreciates them rather than a person who heaves a sigh at the sight of them and promptly begins planning a garage sale.
I would organize a really cool and fun funeral for myself! Of course, I'd be a little too dead to properly enjoy the libations and canapes, but I would like everyone else who was there to enjoy themselves and celebrate, not just my life, but life in general. I'm sure I could arrange to make it a really positive experience for my guests.
I think I would view life differently once I knew the number of days I had left. Instead of stoically waiting for time to pass, like I often do, I would pay more attention to making each hour of each day count. I mean, I already know that I have a finite existence, but because the time left is unknown, it means I could live a long time or a short time more. I believe I'm the same as most other people in assuming that I've got a lot of time left to live (do?) on Planet Earth.
The only thing that would give me pause would be if I knew I was going to die a really horrible death. If so, I would definitely try to either avoid it or mitigate it, which may mess up my Karma or spiritual path in some way.
I wouldn't tell my husband if I knew the time and manner of my death, because I wouldn't want to stress him out. But I would do my best to prepare him in subtle ways about one year in advance, and I would tell him straight up immediately prior so that he could make sure he said good-bye and that his last words to me were not naggy, critical, or otherwise something that he would subsequently torment himself over.
