As we have seen,thefocus of medical care in our society has been shifting from curing disease topreventing disease一especiallyin terms of changing our many unhealthy

behaviors,such aspoor eating habits,smoking,and failure to exercise.The line of thought involvedin this shift can be pursued further. Imagine a person who is about the right

weight , but doesnot eat very nutritious（有营养的）foods , who feels OK but exercises only occasionally , who goes towork every day , but is not an outstanding

worker,who drinks afew beers at home most nights but does not drive while drunk, and who has nochest pains or abnormal blood counts,but sleeps a lot and often feels

tired.This person isnot ill.He may not even be at risk for any particular disease.But we canimagine that this person could be a lot healthier.

The field ofmedicine has not traditionally distinguished between someone who is merely"not ill" and someone who is in excellent health and pays attentionto the body's

special needs.Bothtypes have simply been called "well".In recent years,however,somehealth specialists have begun to apply the terms "well" and"weilness" only to those

who are activelystriving to maintain and improve their body's condition.Mostimportantly,perhaps,people who are well take active responsibility for allmatters related to

their health.Evenpeople who have a physical disease or handicap（缺陷）may be "well" ,in this new sense,if theymake an effort to maintain the best possible health they

can in the face oftheir physical limitations."Wellness" may perhaps best be viewed notas a state that people can achieve,but as an ideal that people can strive for.People who

are well are likelyto be better able to resist disease and to fight disease when it strikes.And byfocusing attention on healthy ways of living,the concept of weilness can have a

beneficial impact onthe way in which people face the challenges of daily life.What is theauthor's purpose in writing this article?
