Catching a germ
Flu and other bugs are transmitted through saliva, so smooching underneath the mistletoe could lead to an unhealthy holiday. Skip the lip lock and go for an air kiss instead, suggest researchers at Ryerson University in Toronto. To further protect yourself from germs, wave hello at parties instead of hugging or shaking hands. Carry hand sanitizer and wash your hands before and after digging into appetizers to avoid infecting others.
