I am sure everyone has heard that to stay healthy you MUST WASH YOUR HANDS before eating, after cleaning, after using the bathroom, and before getting ready to cook. Yes, YOU EVEN SHOULD WASH YOUR HANDS IF PLANNING TO TAKE ANYTHING OUT OF THE REFRIGERATOR!
Also, a person should cover their cough/sneeze. Drink plenty of fluids, eat right and get plenty of rest. Also, avoid people who are sick. AND NOT ONLY KEEP YOUR BATHROOMS AND KITCHENS CLEAN BUT ALSO YOUR DOORKNOBS!
