I'm no Bear Grylls fan. But one thing he had over Dave Canterbury is that Bear didn't lie about his military background. Canterbury served but was outed a while back for fabricating wildly about his record. Most of his high speed, low drag history turned out to be low speed, high drag.

I couldn't believe Discovery kept him on after those revelations, but these days the media has shown that it's perfectly happy with men who steal valor from others.
