　　Whether the hair is long or short, it must be regularly brushed and regularly washed. For greasy(油膩的) hair, especially if the owner lives in a town, it may be necessary to wash the head every four or five days. Those with a dry hair can usually go a little longer, but this is a matter for the individual to decide.

　　1f a woman is not able to go to the hairdresser's very often, it is important that she chooses a style she can easily manage for herself, and this nearly always means that the first cut must be very standard. The same applies to (適用于) permanent waving (電燙). Ideally this should be carried out three or four times a year, so that the hair never gets out of hand.

　　One thing should be remembered though, that is, whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care. Or you may use milder products. As for style, this must be studied according what is the latest fashion and also to suit the individual at different times of her life.

　　Young people who has spots and skin troubles on their face should take particular care to ensure that the hair is both clean and does come into contact with the affected piece of skin. Hair is very difficult to keep completely clean and therefore anyone running their hands through their hair and afterwards touching their face, or letting their hair fall over their faces, might spread from one place to another. Good hair does a lot to the effect of a face, so if you want to look charming, please start the hair.

[　　]

A．having the hair done three times or four times a year.

How Long Can People Live?

　　She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday．

　　Whe n it comes to long life, Jeanne Calment is the world’s recordholder．She lived to the ripe old age of 122．So is 122 the upper limit to the human life span(壽命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?

　　Researchers don’t entirely agree on the answers．“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas．

　　Steve Austad at the University of Texas agrees．“People can live much longer than we think,”he says．“Experts used to say that humans couldn’t live past 110．When Calment blew past that age, they raised the number to 120．So why can’t we go higher?”

　　The trouble with guessing how old people can live to be is that it’s all just guessing．“Anyone can make up a number,”says Rich Miller at the University of Michigan．“Usually the scientist who picks the highest number gets his name in Time magazine．”

　　Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120．Researchers are working on treatments that lengthen the life span of mice by 50 percent at most．So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120．”

　　So what can we conclude from this little disagreement among the researchers?That life span is flexible(有彈性的)，but there is a limit, says George Martin of the University of Washington．“We can get flies to live 50 percent longer,”he says．“But a fly’s never going to live 150 years．”

　　“Of course, if you became a new species(物種)，one that ages at a slower speed, that would be a different story,”he adds．

　　Does Martin really believe that humans could evolve(進化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile．
