Passage 1 A group of scientists have found evidence that coffee beans can help reduce physical
pain. However, they cautioned that since the study was not designed to test coffee’s influence

coffee drinkers and abstainers were similar in all respects except for their consumption.

are 26 to trouble the legions of coffee drinkers looking for any reason not to cut back on
their daily caffeine habit. Coffee, after all, is the apple of their eye.
