Tequila is legendary for teaching hard lessons, and now it's offering them to communities around the world that produce distinctive foodstuffs, according to a North Carolina State University researcher.

It was 1968, and Frank Rochelle was 20 years old and fresh out of Army boot camp when he saw notices posted around his base in Virginia asking for volunteers to test uniforms and equipment.
That might be a good break after the harsh weeks of boot camp, he thought, and signed up.

Even with some of the fanciest technology around -- and an owner who loved him enough to pay for it -- the veterinarians thought Clyde, a burly, loose-jointed Labrador retriever, would be long dead by now.
If the cancer had gotten him, Gloria Mitchell might be dead, too.
