Temple Grandin: It's very hard for humans to imagine that animals are thinking if they're not thinking in words or pictures, right? But I certainly want to imagine as well that they're thinking in smells. How does that actually work? You know, who knew that one could have a better or worse sniff,. But it turns out our sniffs are pretty bad. Their whole anatomy is set up to enable olfactory information to get to the brain. So everything about them is designed to allow them to see the world through smell.
