We every time inspired by someone and make that person hero but according to me bear grylls is areal hero what a person he is.
In that show he use to instruct the people how to escape yourself if you meet such situation.he completly gone to that situation and shows practily how it is possible.because the thing which he did is not usual but can save a life.every one has to watch that show because no body knows when you be in that kind of trouble.
With match box you can eassily burn wood but without that how you can.he is really a hero.
