Open up your home and heart to Rover or Boots. Owning a pet reduces the number of visits to the doctor, prolongs survival after a heart attack, and wards off depression, says James Serpell, PhD, director of the Center for the Interaction of Animals and Society at the University of Pennsylvania. (His family has a cat, a dog, a large green iguana, a bearded dragon, and a dozen fish.)
Pet ownership also protects against a major problem of aging: high blood pressure. In one standout study at State University of New York, Buffalo, stockbrokers with high blood pressure adopted a pet. When they were faced with mental stress, their BP increased less than half as much as in their counterparts without animal pals. But pick your pet with care. There is nothing stress-reducing about a dog that chews the baseboard to bits.
