By how many orders of magnitude? Would you play Russian Roulette for $10/day? It seemed to me that implicit in your argument was that even if someone disagrees with you about the expected value, an order of magnitude or so wouldn't invalidate it. There's a rather narrow set of circumstances where your argument doesn't apply to your own situation. Simply asserting that you will sign up soon is far from sufficient. And note that many conditions necessitate further conditions; for instance, if you claim that your current utility/dollar ratio is ten times what it will be in a year, then you'd better not have turned down any loans with APY less than 900%.

And how does the value of cryonics go up as your mortality rate does? Are you planning on enrolling in a program with a fixed monthly fee?
