As the saying goes, the face of the soil back towards the sky, this is the symbol of the rural people, rural people are generally based on planting crops, they are all year round in the laborious planting of crops. For the countryside can not stand up to the waist, hunchback of the elderly a lot, while the city is almost no, this is why this problem . I think most of this is related to their own environment, as a rural people, they do not have other sources of income, every year in the spring have to be sown, but also breeding livestock, often back dung ah, back potatoes ah, back maize, etc., so that the long-term past waist will have been not up.
And when it comes to plowing, the hoe is in your hand, and you're plowing, so you're facing the dirt. The people in the city are generally more leisure time, their source of income do not have to worry about, their own children will provide for their own, usually they will go to the square dance, the disease is also less, there is no back pain, leg pain and so on the occurrence of the situation. But as rural people planting crops is their mission, even if the back can not stand up, they also feel worthwhile.
There is another aspect of the rural people in the diet is not as high as the nutritional value of the city people eat, they usually eat some light meals, as long as they can solve the problem of hunger on the line, and the city people then pay more attention to the nutritional value of food, you can often drink high-calcium milk, or a little bit of small injuries and illnesses go to the hospital for treatment, but also inside the city of the level of medical care than the countryside is high.
Of course, there is another situation is the individual's own reasons, it is possible that the quality of the countryside people's beds is not very good, in the sleep of the sleep position is wrong. Either the beds are too hard, or the pillows they are padded with are a bit high. And the city people's family conditions are better, the beds set up in the bedroom, but also according to their own physical condition to set up, are generally more suitable for the elderly to rest, may also come with some of the function of health, so combined with the above reasons, this is probably the countryside people hunchback is more, and the city people do not have the reason.
