Send a holiday card to feel more connected

Never underestimate the power of a cheery ho-ho-holiday note or the fun of decorating the mantle with Season's Greetings cards framed with the smiling faces of friends and family.

Holiday cards deliver health benefits, says a study by Penn State University. "People feel more socially embedded and connected to others when they receive cards," says lead researcher Karen Fingerman. "Older adults also feel a connection to their past when the personal message is sentimental or from a long-time friend."

Spread some cheer: Mail local cards by December 19 to make sure your loved ones receive them on time.
