I got a press release today from Smithsonian magazine. Certainly grabbed my attention. Here's the top:
"Understanding the smile is serious business. For example, did you know that the freshly severed heads of executed criminals and revolutionaries were the first specimens used to study the mechanistic nature of human facial expressions? Over 150 years later, scientists can confidently say that facial expressions are innate. Facial expressions, and especially the smile, constitute a system of unconscious communication that got built into our biology long before language itself.
The August issue of Smithsonian magazine explores how scientists are finding there is a lot more to one of the most complex human expressions than meets the eye."
I knew I should have renewed my subscription this year.
