每个人都希望自己健康，那么什么才是健康呢？ 过去，人们认为健康就是指身体不生病。 但是，现在人们认识到，健康还指精神上的健康。 只有身体和精神都健康，才算是真正的健康。 有一位教授用数字来说明健康有多么重要：要是健康是1，其他都是1后面的0；如果没有1，不管有多少0也没用。 所以我们平时一定要注意锻炼，别等健康出问题了才后悔。

Everyone wants to be healthy, so what is health? In the past, people thought health simply meant the body not getting sick. But now people realize that health also means mental health. Only when both body and mind are healthy is it true health. A professor used numbers to explain how important health is: if health is 1, everything else is the zeros after 1; if there is no 1, no matter how many zeros there are, it's useless. So we should make sure to exercise regularly; don't wait until health problems arise to regret it.
