Red meat kills. Sunshine and fresh air are good.

More health news that should shock no one:

A National Cancer Institute study found that people who eat the most red meat and the most processed meat have the highest overall risk of death per year from all causes, including heart disease and cancer.

And the World Health Organization says that sunshine and fresh air can reduce the risk of tuberculosis in hospitals and prisons. (One interesting fact: while many of us worry about catching some nasty airborne disease on an airplane, according to the director of the WHO's Stop TB department, Mario Raviglione, "In airplanes the ventilation system is actually better than in most buildings.")
