We all tried to finish a 32 oz. steak in Canada when we had just come off a survival course in the Bush for 10 days without any significant food available except what we could catch. Trouble was, the animals knew very well to keep away from where they held the survival courses! They were no fools
Not one of us could finish the steak because our stomachs had contracted so much during the course, so we all had to pay!
The place selling the steaks knew the score as well and that they were 100% safe with the challenge!
