This is a book that starts out well with hard facts and figures but wanders off into the realm of speculation and anecdotes when the facts begin to dry up. The problem seems to be that after all his travels and research the author didn't have any solid data of his own so he starts to draw some pretty tenuous conclusions. Several of the chapters are bookended with the stories of researchers who have endeavoured to prove some incredible fact about survival rates (left-handers live shorter lives than right handers, people with "positive" sounding initials live longer) only for the author to admit that these are at best controversial, and at worst completely unproven theories. The chapter on religion is especially frustrating in this regard; as expected the author is fairly skeptical of the idea that prayer or belief can be beneficial to survival but seems unable to simply admit that his conclusion is "I don't know" and tries to force an answer that perhaps religion is of benefit despite having little evidence outside of anecdotes. The huge great elephant in the room is that he is speaking to the survivors, so of course they are likely to claim to have received some benefit from their faith that helped them overcome terrible adversity. It's as if the author has never heard the line about the "opium of the people". Sometimes it's actually quite insulting and a little bit ugly; take the two pilots who ejected from their jet at well past the speed of sound. One died instantly, torn apart by the aerodynamic forces. The other was terribly injured but survived in his life raft until help arrived. The simple facts are that he was lucky - he was a different build to his colleague, and a fortunate wave washed him into the liferaft. And the author does acknowledge these points but then spends pages pontificating on the man's faith in God and how it may have helped him. He even brushes over the man's mention of the strength he got from thoughts of his family. Not a mention of whether his dead colleague was a man of faith too.
Despite these frustrating flaws it does have some interesting nuggets scattered about it though most of these are from "proper" researchers (ie: people with more than just stories) and people with expertise. And if you have never encountered any of these factoids and ideas before (I have read a few books previously on air safety and the psychology of fire safety) then I can imagine that some of this knowledge may be useful for daily life. Certainly the simple advice that merely thinking about potential scenarios, and how one might escape in the even of disaster boosts one's chances is something everybody should consider. Compared to the advice of those in the know, and those who have spent lifetimes studying the mechanics of surviving, the author's own 'Survivor IQ' at the book's conclusion is superfluous to requirements. I barely skimmed over it.
So it's mostly a book of anecdotes and these are gripping, life-affirming, uplifting, inspiring and all the other words. There are some very brave people with extraordinary stories to tell. And if it does save your life one day then it was money well spent.
