A new study in Preventative Magazine revealed that having a pet--specifically, a dog--adds roughly 10 years to your life!

The study examined the lives of about 500 elderly people (average age 79), and found that the people with dogs had notably lower levels of stress, anxiety, and depression. They also got more physical activity in their day than people without dogs. The added activity was a boost to their immune systems, and contributed to better muscle strength and stronger bones.

So, get a dog = look & feel younger!
