I was given a prediction of 95 years, although I suspect it would have been less if the quiz included questions such as "Do you handle deadly snakes on a daily basis?" and "Do you have a history of being in life-threatening situations such as skydiving mishaps, getting caught in rips, ending up stranded and unprepared in the wilderness etc?" and "Do you have a history of doing stupid things like going SCUBA diving and skydiving on the same day, getting zapped by 240volts and getting severely lost while bushbashing, and does this history include far too many trips to hospital without many of which you would be dead?"
Then again, maybe that would be balanced if it included questions such as "Have you escaped against the odds from situations like being caught in a rip, being in the middle of the black Saturday fires, that incident in Texas you shouldn't mention on ASF, etc?"
I'm a bit sus about the accuracy of questionaires at the best of times.
