The claim that a person's breath is 80% of what a deer smells, sure seems like a scam to me. Anybody who eats a few cloves of garlic and drinks a couple of bottles of wine is going to have some high octane breath for sure- breath that a deer in the next state can smell. On a normal diet though, I doubt that breath is what a deer picks up when it smells you. They mostly smell your dead skin.
