I saw this on io9 yesterday, and as the video actually requests for all viewers to share then you are the people I've chosen to infect. It begins with a premise: are thoughts germs? Can they be transmitted from one person to another? Watch this and explore the psychology of how a one-standard deviation increase in the amount of anger an article evokes can increase the odds (for example) that it will make the most e-mailed list by 34% on The New York Times. Sure, it's a wee bit long but it has advice that should you follow it, may just aid in helping you keep a healthy mind. And who doesn't want a healthy mind?
