Lice (twitpic|@bug_gwen)

The head to head contact that occurs when people lean in close to snap a picture, is creating a pathway for lice to travel from one person's head, to the next, according to lice-treatment treatment expert, Marcy McQuilian. 

A nurse in Atlanta told CNN that she can vouch for the validity of the theory because of the recent spikes in lice cases she has seen amongst people in their teens and early 20s, the age group most notoriously known for taking selfies. 

However, doctors in California beg to differ. 

Doctors at the University of Southern California School of Dermotology told KTNV that the contact time is so short, that it is unlikely that lice would be able to move from head to head during a selfie, because lice do not jump. 

The theory is still being investigated by doctors nationwide, but just in case, you may want to refrain from today's daily dose of selfies.
