Why has the childhood competitive game "sandbag throwing" disappeared?

Why did the childhood competitive game "sandbag throwing" disappear? I think the main reason is the times in progress, the development of science and technology, and the change of the social environment, I will be the childhood competitive game throwing sandbags into the disappearance of the reasons for the following three points:

First point: the change of the social environment, I remember when I was a small boy, because my family lived in the village, the children are more, go to school in a school, basically, and all the children know each other, in school, a class, even if only 10 minutes of recess time, the children will be able to play the game of sandbags. Even if there is only 10 minutes of recess time, we have to go down to the crazy one, playing sandbags, jumping will be ribbons, when playing sandbags is not exclusive to boys, jumping ribbons are not all girls. To the end of school, the schoolbag can not put, busy to play sandbags, not until dark do not go home, often are parents to find out, ask, are going to eat not go home, one by one by their parents "carry" home, but also do not forget each other about tomorrow to continue, be sure to distinguish the winner from the losers at that time, we do not know what is called a smartphone, what is the king of glory, what is the king of glory? What is the King of Glory, with the development of science and technology, social progress, the popularity of smart phones, now even elementary school students every day are about to open black, about to play the King, I think they are now rarely see the sandbags, we play sandbags, not only will buy sandbags, because buy sandbags, the inside of the loaded stuff is relatively light, not far to play the old open line, so then you often see the cloak of the hair of the little girl! So at that time, you will often see a little girl with a hairdo running around to avoid the attack of the sandbags, don't be surprised, her hair ring is just tied to the sandbags. After that, we started to make our own, looking for nice fabrics, a bunch of kids sitting together, not letting the adults help, sewing them up crookedly, stuffing them with corn kernels or fine sand.

The second point: I have to say that now the children's academic task is really heavy, all the children's parents are the same, not willing to let their children lose at the starting line, from kindergarten onwards to report a variety of special classes, on the school is to participate in a variety of remedial classes, the weekend break, summer and winter vacations, the morning math, the afternoon of the English language, and at night have to go to the special classes, so the children's academic task is heavy! is also one of the reasons why the childhood competitive game throwing sandbags disappeared.

The third point, now the children, parents are very uneasy about the children to go out to play, news reports have heard too many traffickers abducted children, especially now we are more looking at the enjoyment of the spiritual level, parents are willing to let their children go out to see more, so now parents are willing to take their children out to travel, or as little as possible to let the children go out to play. This is also caused by the disappearance of the childhood competitive game throwing sandbags.

But ah, went to college, a group of us run two children will still be in the summer not on the evening study time out of the date to play a sandbag, of course, this is a minority. But, seriously, you can still find the flavor of childhood oh.
