Since I saw this on tumblr.. (I didn't reblog this one, because I don't have an account there.) I saved this on my computer and instead of reblog this gif photo, I decided to post this here on my page. It has credits to the owner btw. :D Aside from its a gif, it tells all the benefits of smiling... that I supposed to blog today. 

Wear your smile! {◕ ◡ ◕}
