Pugs: Apply directly to forehead

Dogs work better than Prozac, says a researcher at the University of British Columbia in Canada. Having a familiar, friendly dog close by lowers blood pressure, slows heart beat and relaxes muscles, all signs of reduced stress. And the pooch's effects work faster than antidepressants too.

A study of seasoned citizens found the old codgers make fewer visits to the doctor and are generally more physically active. Guess when business is picking up you get a lot of exercise.

Want to get the benefits but aren't ready for your own dog? Try taking care of someone else's dog for a few days. Or sign up at a local shelter for their volunteer dog-walking program. You'll get the benefits of a good walk and will have longer arms.
