I wonder at what age does a person start
getting influenced by other people’s yawns. I was noticing
today that when Lex yawns, I usually yawn too. But when I yawn
it seems to have no impact on him. I’ve read that contagious
yawning is a social thing and anthropologists believe it helped
tribes of people maintain similar sleep cycles… so you’d
think that the contagious yawn reflex would kick in pretty
early in life. Hmmm…. another FTI project. Remind me to tell
you all about FTI someday…
