Guide to Air Kissing

• While a firm hand shake is more socially acceptable, hygienists claim it is less healthy
• For a germ-free air kiss, it is important first to decide which cheek to aim for, if only to avoid an embarassing interlocking of noses
• Social etiquette expert Liz Brewer advises that it is best to lean towards the right cheek, so you can give a more friendly "heart-to-heart" kiss
• By only touching cheek on cheek, you should be able to avoid picking up unwanted germs from the person you are kissing
• Should you be caught off guard by an actual kiss, fear not, as lip contact is still less likely to transfer infection than touching each others virus-laden hands
