Experts have confirmed a rather gross way to boost your immune system, pick your nose and eat it.
Dr. Meg Lemon of Colorado believes people shouldn't have so much fear when it comes to germs. "You should not only pick your nose, you should eat it," said Dr. Lemon.
Dr. Lemon is also an advocate of eating food that has been dropped on the floor saying "please pick it up and eat it".
The number of those with allergies has gone up in in Western societies, in large part due to people trying to keep the environment around them really clean.
"Get rid of the antibacterial soap," Dr. Lemon says. "If a new vaccine comes out, run and get it. I immunized the living hell out of my children. And it's O.K. If they eat dirt."
