I've had a fair number of relatives die. This is actually one reason I'm delaying on cryonics right now. I first got strongly interested in cryonics about 6 months ago. Then shortly after that, multiple relatives of fairly young ages died fairly suddenly. They weren't the first such deaths in my family by any means. And a family friend died at about the same time from cancer that he had had for a very long time. The initial reaction was that I should run off and sign up for cryonics right now. So I'm now delaying in part to make sure that I am making the decision more rationally and not just based on sudden recent events clouding my judgment. That and the whole thing with cryonics being fairly expensive for a grad student budget are the main causes of not signing up at this point.
