Wasn't someone on the list looking for a life expectancy calculator? Here's one at MSNBC. Well, you know how much I love polls.
Hypothesis: Extropians, being extropic and all, are more likely to take action to maintain a healthy lifestyle. Therefore, they will have longer life expectancies on the average than the rest of the population (not quite sure of what that is).
My LE = 86.39
Not good enough!
