The dorm bathroom, that multi-use gathering place of students, is a veritable germ farm. And it's no wonder. There are 100 trillion bacteria on and in the human body, an amount that translates to about 5 pounds (2.2 kilograms) of microscopic critters. If you were to corral all the bacteria in your body, they would form a mass about the size of your liver [source: Allday]. Now multiply that number by 12 or however many people use the bathroom regularly. Gross, right?
Some bacteria play important roles while others cause problems. While one type of bacteria may regulate intestinal health, another may cause gut-twisting food poisoning.
You can tip the odds in your favor by improving the cleaning routine in one place germ-ridden danger lurks (no, we're not referring to the college cafeteria). Fight back by cleaning the 10 places everyone else has forgotten.
