The hidden power of smiling - Ron Gutman 

So many years later this is still my favorite Ted Talk ever ❤

Smiling is infectious, u catch it like the flu, when someone smiled at me today I started smiling too. I walked around a corner and someone saw my grin, and when he smiled I realised I'd passed it onto him. I thought about that smile I'd smiled and understood its worth,a single smile just like mine could travel round the earth,so if u feel a smile begin don't leave it undetected, let's start an epidemic quick and get the world infected. :o)

Do anyone know how to do this ppt?

One smile can generate the same level of brain stimulation as up to 2000 bars of chocolate!!!!!!!
