When forests disappear, migratory (遷徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification. Bird Friendly coffees are shadegrown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shadegrown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more plex flavor. Bird Friendly certified coffees grow under biodiverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet. Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional ine. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat. Buying Bird Friendly supports the Smithsonian Migratory Bird Center39。s conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.（1）What is the present situation of coffee farms?

Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people39。s increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy. When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So
