22、In many parts of the world，people live to a healthy old age．What is the secret of their long lives? Three things seem to be very important：fresh（新鮮的）air，fresh food and a simple way of life．The Hunzas，people who live in the Himalayas（喜瑪拉雅山），are famous all over India for long and healthy lives．They work near their homes in the clean mountain area．They do not travel a long way by bus，car or train．They do not sit all day in busy offices or factories．They take more exercise and eat less food than people in cities．They eat vegetables grown by themselves．They drink milk taken from their own cows．They do not need doctors，for there are not many illnesses．They are happy and quiet．

    根據(jù)短文內(nèi)容判斷正誤，正確的在括號(hào)中寫“T”，錯(cuò)誤的寫“F”。
