江苏省南通市通州区2018-2019学年高二上学期期末联考英语试卷(音频暂未更新)
Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when wβfinally clean up our act.
If the evidence for how wrong the first idea is isn't apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?
To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.
The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.
The effects of some bad habits-smoking, in particular-can haunt you for decades. But the damage from other habits can be largely healed.
“Any time you improve your behavior and make lifestyle changes, they make a difference from that point on.” says Dr. Jeffey Koplan. “Maybe not right away. It's like slamming on the brakes. You do need a certain distance.”
But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research: —A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month. —The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won't cure all that bothers you, of course. But doctors believe that many chronic diseases-from high blood pressure to heart disease and even some cancers-can be warded off with a few sensible changes in lifestyle.
Not sure where to start? Surprisingly, it doesn't matter, since one positive change usually leads to another. Make enough changes, and you'll discover you've adopted a new way of life.
