Coming home from work tonight, I drove past someone (driving in the approaching traffic) who was yawning a big, open-mouthed yawn and it made me yawn immediately! That got me thinking about whether or not yawns truly are contagious or if it's just our imagination. As I started looking up articles on this: this one & this, I began to yawn & continue to as I write this post.
Yawns definitely are contagious, especially to me! I must be very empathetic, or closer to the chimpanzees than I like to think!
