Is having a bad habit ever a good thing? It kind of can be if your aim is to lower your blood pressure, since one way to do that is to reduce your alcohol consumption significantly.

Recently, one of my colleagues, a pediatric gastroenterologist, told me about a teenage boy who had come to see him because of severe stomach pain he'd had for about two months.

Think coffee's just the drug of choice for humans looking to stay alert? Scientists have some eye-opening news for you: Bees get a buzz when they drink nectar laced with a little caffeine, and it supercharges their long-term memory. In laboratory experiments, honeybees were roughly three times as likely to remember a floral scent a day later if the nectar had a minuscule amount of the stimulant than if it was caffeine free. They were also twice as likely to remember a caffeine-laced scent a full three days later.
