According to the Better Report, “A dog’s sense of smell is about 100,000 times more sensitive than a human’s, which means they predominantly learn about the world through their noses. Dogs can learn all they need about another dog by sniffing their rear end, where scents are most concentrated. Every dog’s odor is unique. A quick sniff helps them determine whether they’ve met before, along with the other dog’s gender, reproductive status, temperament, health status, and diet.”\
Studies show the information gathering via the nose/butt connection may be just as strong in humans. You can help by trying this with a complete stranger and report back to me with the results. I will gather the information and report the results to the scientific community; that is, after I have a good laugh, violate your confidentiality and subject you to biting ridicule. Hopefully you will learn a lesson and never sniff in public again.
You’re welcome.
