Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化物) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers, with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”, or problems with daily activities or basic needs, such as dressing or bathing.
Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (缓冲) against disability, Tomata’s team did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting (凝固).

In 1943, Tsien and two others in the Caltech rocketry group drafted the first document to use the name Jet Propulsion Laboratory. During the Second World War, he was amongst the other scientists participated the "Manhattan Project" .After World War II he served as a consultant to the United States Army Air Force. During this time, Conlonel Tsien worked on designing an intercontinental space plane. His work would inspire the X--20Dyna-Soar which would later be the inspiration for the Space Shuttle.

In September 1955 he was permitted to leave for China, where Tsien resumed his research, founded the Institute of Mechanics, and went on to become the father of China's missile program, a trusted member of the government and Party's inner circle, and the nation's most honored scientist, Tsien retired in 1991 and has maintained a low public profile in Beijing, China. The PRC government launched its manned space program in 1992 and used Tsien's research as the basis for the Long March rocket which successfully launched the Shenzhou V mission in October of 2003.The elderly Tsien was able to watch China's first manned space mission on television from his hospital bed.
In his late years, since the 1980s, Tsien devoted himself to spirituality research, and advocated scientific investigation of traditional Chinese medicine, Qigong and "special human body functions".
