Believe it or not, your tongue is conected to your hands through fine motor movement. What happens everytime you do something very detailed...like threading a needle? Your tongue comes out and even contorts as you concentrate on getting that thread through that little hole.
Take note of this type of intricate and thoughtful work...your tongue will automatically help you get the project done.
How facinating......I notice older people do that when signing their name....also cutting their toenails.
ya there is this guy that always sticks his tounge out when i see him i wonder what it means
I stick my tongue out sometimes when I'm concentrating really hard! I didn't know anyone else did that. I found out when I was learning how to drive and my mom pointed it out to me.
