Want to look younger? Forget the plastic surgery ... and get a dog.

Scientists say having a dog can make you look and feel 10 years younger. Why?

According to researcher Dr. Zhiqiang Feng, of St. Andrews University in Scotland, "If you have a dog in the home, your physical activity level is roughly equivalent to a person 10 years younger. 

"It may not add a decade to your life, but it is very beneficial – it is all about getting up and out and about."

Having a dog is not only good for your physical health, but it's good for your emotional health as well.

"On average dog owners have lower levels of depression," said Dr. Feng. "The bond between pet and owner benefits people’s health generally." (Daily Mail
