Researchers at the CDC have found that the posting of lenny is directly linked to autism. The study involved 500 teens between the ages of 12 and 18. Teens were asked to use their favorite forum for a period of 2 hours a day over one week. The result after the 14 hours showed that the teens using the "lenny" face had previously been diagnosed with autism or aspbergurs. The teens tended to prefer 4chan at 47%, Bungie's Destiny App at 33%, 19% for Reddit, and the remaining 1% using other various forums. Http://www.cdc.gov/studies/internet/autism.html
