A delightful, witty investigation into the mysterious world of an ailment that touches every life on the planet on average four times per year. And the multi-billion dollar industry that repeatedly (and wrongly) claims to “cure” it. A gifted science reporter, Ackerman takes us deep into the places where the viruses begin their nefarious onslaught (the nose) and delights in relating the studies that debunk the curative effects of chicken soup, zinc, and various soaps and elixirs. But she also tells us what works. And how to avoid a cold (hint: children are germ factories).
