This may be a little bit surprising to some people. Everyone has taken cough syrup. But that's why medical research continues to be done.

Cough syrups don't treat the underlying cause. They won't make you better any faster.

Cough syrups may suppress a cough a little bit. But they don't treat the underlying cause. They won't make you better any faster.

That's a general problem with biomedical research -- it's hard to attract the people who may need it most.

The theory behind previous research is that people with higher education have a higher brain or cognitive reserve, maybe a larger number of brain cells or more efficient brain systems or networks. These people with higher education have more redundancy or reserve so they can cope if part of the brain is destroyed.

Research tells us that most Americans don?t understand that antibiotics kill bacteria, not viruses. People go to their doctor and request antibiotics for themselves or a sick child, when it is not the appropriate course of treatment.
