　You might not know it, but there is something wonderful at your fingertips. You can make people happier, healthier and more hard-working just by touching their arms or holding their hands.

Doctors say that body contact(接触) is a kind of medicine that can work wonders. When people are touched, the quantity of hemoglobin (血红蛋白) - a type of matter that produces the red color in blood increases greatly. This results in more oxygen (氧气) reaching every part of the body and the whole body benefits. In experiments, bottle-fed baby monkeys were separated from their mothers for the first ten days of life. They became sad and negative. Studies showed the monkeys were more probable to become ill than other babies that were allowed to stay with their mothers.

Human babies react (反应) in much the same way. Some years ago, a scientist noticed that some well-fed babies in a clean nursery (托儿所) became weak. Yet babies in another nursery were growing healthily, even though they ate less well and were not kept as clean. The reason, he concluded, was that they often had touches from nurses.
