Lung specialist, Dr. Friedrich Bischinger, has been quoted as saying "With the finger, you can get to places you just can't reach with a handkerchief, keeping your nose far cleaner. And eating the dry remains of what you pull out is a great way of strengthening the immune system." However, many doctors disagree. Our fingers are covered in germs and bacteria from touching things like doorknobs, restrooms and phones. If you then use that germ-covered finger to pick your nose, you risk transferring all those germs in to you body. So, if you want to reduce your germ intake, keep that finger to yourself.
