How Randomness Rules Our Lives

Senses that humans have also are very poorly developed, certainly compared to other species. For example, our sense of smell is positively terrible compared to those possessed by some species imean. We can pick up the smell of another human being from sweaty clothes that they're wearing but we can't track them across distances like dogs do. A good bloodhound can track the scent of a human that's 300 hours old for more than 12 days. And he can low that scent up to a hundred and 30 miles, or 200 kilometers.
