Actress-author Joan Collins refuses to shake hands, hug or kiss her friends or co-stars anymore because she doesn't want to catch their germs. "I try to avoid shaking hands - instead offering my jaunty closed fist for a gentle bump, which is usually met by a puzzled expression unless the recipient is approaching puberty - much less this ghastly fad of kissing and hugging strangers," she told Daily Mail.
