Bioengineers at Work

Dr. Friedrich Bischinger, a lung specialist in Austria, believes that "people who pick their noses with their fingers are healthy, happier and probably better in tune with their bodies". This is because the nose is a filter where a lot of bacteria is collected, and he believes that if the dry remains are ingested, they work just like a medicine when it arrives at the intestine and helps strengthen the body's immune system. He also points out that children pick their noses instinctively, not imitating adults, but stop as adults because it is considered disgusting and anti-social. There are some possible negative effects, such as breaking the skin inside the nose, and most doctors recommending avoiding germs all together. This may not be factual, because no formal study as been done, but I thought it was an interesting theory.
