“I’m so tired from smiling”. This is one of the most common comments I have heard during weddings. Some say it takes lesser muscles to smile than to frown. A check on the internet (because if it’s on the internet, it has to be true) shows that it takes 10 – 12 muscles to smile and 6 to frown, but because one tend to smile more often than frown, those muscles tend to be better developed. That said, my Sergeant during NS concluded that if you are posted to AI (Armour Infrantry), you will lose your ability to smile forever. If you find yourself feeling tired from smiling, maybe you should try working on those muscles more.
