I won't be heartbroken, because even the working people in the city, even those white-collar workers, are busy working overtime and staying up late a lot. Although it looks white, but the heart is also very tired, the body is also a serious overdraft, including myself is also so. Rural elderly lean and thin, in fact, this is precisely because after a long period of work at the site, the body's muscular, physical quality is very good, you have to take things, a lot of city people can not compare to such a rural elderly, they are more healthy.
