If only it were that easy to get rid of those nasty flu bugs that lurk everywhere doorknobs, keyboards, phones. Things you touch every day.
Flu is definitely a hands-on kind of experience.
Use soap and warm water before meals or after contact with sick people. Meanwhile, keep your hands away from your face. Most bugs sneak in through the mucous membranes in your nose, eyes, or mouth. If your doctor agrees, exercise regularly. Studies suggest that regular exercise boosts the immune system.
