Among various factors that contribute to todays longevity of people are three most obvious ones: the improvement of food conditions, the development of modern medical technology, and finally current stability of economy in our country. Food conditions are better than before and are still being developed with a rapid pace. First of all, foods are more hygienic. people today drink untainted mineral water, sterilized skim milk, which are cheaply supplied in supermarkets. Furthermore, foods are more nutrient. Not to mention various carefully designed nutrient products. people can just ignore the possibility of being dystrophic, since they can keep nutrient balance by simply taking a cheap pill of vitamin compound every day. Another essential improvement that contributes to peoples longevity is swiftly developing medical technology. Development of modern medical technology has always been amazing. Certain diseases such as tuberculosis, pneumonia, and dysentery are now easy to remedy with low expenses, but in the past, they are all probably lethal ones. The dental technology seems developed little except its exorbitantly charged bill, yet the simplest technology contributes to peoples longevity most. It is not difficult to imagine that if an individual who lived in the past got a toothache, without certain dental care which is common today, he was certainly in an awful prospect: he might even die of a toothache! Current societal and economic stabilization is also a very indispensable factor. people have less pressure in a more stable society, the less pressure they suffer, the healthier they are. Todays ideal stabilization even provides people an opportunity to secure their futurebuy insurances. Various types of insurances are readily available, which make people feel safe, and have to a large extent reduced people anxieties, and therefore indirectly contribute significantly to the longevity of people.
在促进人们长寿的各种因素中，有三个最为明显的因素是：食品条件的改善，现代医疗技术的发展，以及当前我国经济的稳定发展。食品的情况比以前更好，并且正在迅速发展。首先，食品更卫生。今天没有人喝矿泉水，消毒脱脂牛奶，这是在超市里低价供应。此外，食物更营养。更不要提各种精心设计的营养产品。人们可以忽略营养不良的可能性，因为他们可以通过简单地以一个便宜的复合维生素丸每天保持营养平衡。促进人们长寿的另一项重要改进是快速发展医疗技术。现代医疗技术的发展一直是惊人的。某些疾病，如肺结核、肺炎和痢疾，现在很容易用低费用来弥补，但在过去，他们可能是致命的。牙科技术似乎发达小除了过分昂贵的账单，但最简单的技术，有助于人们长寿的最。这是不难想象，如果一个人谁住在过去牙疼，没有一定的牙科护理是常见的今天，他是肯定一个可怕的前景：他甚至可能死于牙疼！目前的社会和经济稳定也是一个非常不可缺少的因素。人们在一个更为稳定的社会中压力较小，他们遭受的压力越小，他们的健康就越健康。今天的理想稳定甚至提供了人们一个机会去确保他们的未来购买保险。各种类型的保险都是现成的，这让人感到安全，也在很大程度上降低了人们的忧虑，从而间接地有助于人们的寿命明显。
