以前从无心脏病的人,随年龄增长或步入老年以后,渐渐地力不从,早上买菜回家,提了一篮菜,以往可以一口气到家,而现在必须由途停一停喘口气,再继续前进。登楼梯,原来可以一口气上三楼,现在走上二楼,必须放下东西,站上几分钟,叹上几口气再继续上楼。心中有事,急步赶路,可没走几步路,便感到喘不过气来,非得站停,把气缓过来再走。人说,老了,不中用了。 In the past, people without heart disease gradually became less able to work after they grew older or entered old age. In the morning, they returned home to buy vegetables and brought in a basket of vegetables. In the past, they could get home in one breath at a stroke, Then move on. Ascended the stairs, turned out to be on the third floor, and now embarked on the second floor, you must put things down, stand a few minutes, sigh a few breaths and then continue upstairs. Something in my heart, hurried hurry, did not take a few steps, they feel breathless, had to stop, the gas slowly over. People say, old, useless.
