Smile

Caleb and I had a quick breakfast together this morning. In the middle of his doughnut, he looks up and smiles and says, "Mommy, did you know that when you smile you exercise 30 muscles?" It was cute, even cuter than "The human head weighs eight pounds."
I got to thinking about it and smiling has lots of benefits.
1. Smiling makes us attractive.
2. Smiling Changes Our Mood
3. Smiling is Contagious
4. Smiling Relieves Stress
5. Smiling Boosts Your Immune System
Smiling helps the immune system to work better. When you smile, immune function improves possibly because you are more relaxed. Prevent the flu and colds by smiling.
6. Smiling Lowers Your Blood Pressure
7. Smiling Releases Endorphins, Natural Pain Killers and Serotonin
8. Smiling Helps You Stay Positive

Wow, I can't get a ton of exercise these days with being pregnant and all, but I can smile. If it has all of these benefits as well as working over 30 muscles...i'm doing pretty good!

So, take a hint from a 6 year old. Smile.
