The enormous capacity for viruses to change over time is discussed in Chapter 10.
This brand of science may eventually give us an answer to a question about how to prevent and treat colds. But we cannot know if it is the best answer unless we try out all the potential treatments. We also will not know if any treatment that seemed to be effective was simply one that we tried at the right time—when our cold was getting better anyway. Luckily for us, legions of professional scientists spend their time trying to answer questions such as these. Scientists use the same basic process of testing ideas about how the world works and discarding (or modifying) ideas that are inadequate.
If we give zinc lozenges to one volunteer and placebo lozenges to another, it is likely that the two volunteers will have colds of different lengths. But even if the zinc-taker had a shorter cold than the placebo-taker, you would probably say that the test did not tell us much about our hypothesis—the zinctaker might just have had a less severe cold for other reasons. Now imagine that we had 5 volunteers in each group and saw a difference, or that the difference was only 1 day instead of 3 days.
