Today I would like to tell you about the effects of old age on health. Actually today a lot of improvements have taken place in the care of old people and old people's health is not nearly so bad as it used to be.
Probably many of the fears that people have of growing old are greatly exaggerated. Most people, for example, dread becoming senile. But in fact very few people become senile. Perhaps only about 15% of those over 65 become senile. Actually a much more common problem is in fact caused by we doctors ourselves. And that is over-medication. Nearly 80% of people over 65 have at least one serious illness, such as high blood pressure, hearing difficulty or heart disease. And very often to combat these they take a number of drugs and of course sometimes there are interaction among those drugs as well as simply being too many. And this can cause a lot of complications from mental confusions, very commonly, to disturbance of the heart rhythm. So this is a problem that doctors have to watch out for.
Probably the most ignored disorder among old people is depression. Maybe about 15% of older people suffer from this condition. A lot of it is caused by this over-medication which we mentioned.
Although it is better now for old people, we have to admit that the body does change as we grow older. The immune system starts to decline and there are changes in metabolism, lungs, the senses, the brain and the skin.
So what should an old person do to counter-act these changes?
He or she should eat a balanced diet—not too much fat—chicken or fish should be eaten rather than eggs or beef. Eat more high fibre and vitamin rich foods, such as vegetables and fruit.
The old person should give up smoking if he hasn't already done so. He should also do regular exercise—at least half an hour, three times a week. No section of the population can benefit more from exercise than the elderly.

今天，我要告诉你的影响，对健康的晚年。其实今天很多的改进发生在照顾老人和老人们的健康是没有如此糟糕，因为它曾经是。
可能许多人担心，日益岁是大大夸大了。大多数人，例如，害怕成为老年。但实际上很少人成为老年。也许只有约15 ％的人成为65岁以上的老年人。实际上是一个较为普遍的问题实际上是医生造成的，我们自己。这是过度用药。
近80 ％的人超过65岁至少有一个严重的疾病，如血压升高，听力困难或心脏病。并常常为打击这些他们采取了一些药物，当然有时有这些药物之间的相互作用，以及仅仅是太多了。这可能会导致很多并发症，心理
升混乱，非常普遍，对干扰的心律。所以这是一个问题，医生需要提防。
也许是最被忽视疾病是中老年人抑郁症。也许约15 ％的老年人患有这种疾病。很多是造成这种过度用药，我们提及。
虽然最好是现在的老人们，我们必须承认，该机构没有变化，因为我们长大。免疫系统开始下降，有改变，代谢，肺，感官，大脑和皮肤。
因此，应该怎样做一个老人反行为这些变化？
他或她应均衡饮食，而不是过多脂肪的鸡肉或鱼应该吃，而不是鸡蛋或牛肉。多吃高纤维和维生素丰富的食物，如蔬菜和水果。
旧的人，应该放弃吸烟，如果他没有这样做。他还应该做定期锻炼，至少半小时，每周3次。没有任何部门的人口能够更多地受益于行使比老人。
