A Load of old Gob Rot

Scientists can talk a load of of old rollocks.

Scientists at the universities in Navarra in Spain and Catania in Italy claim that drinking more than 4 cups of coffee a day can prevent Type 2 Diabetes and hypertension.

If that's the case, how come I, who drank a damn sight more than 4 cups of coffee a day for over 30 years, still got both?
