In history, there are actually many inventions that deviate from the original intention of the inventor. Several of them are particularly special and attract much attention. Here are two of them as representatives to introduce to you.
First of all, there is the treadmill. The treadmill was invented as a punishment tool in ancient times. Most people who committed crimes would be arranged to run on the treadmill in the cell. This running is certainly not what everyone thinks. It's so simple. Sometimes there are some nails placed on the treadmill, and you have to keep running on it. Of course, it also takes a very long time. Sometimes you run for several hours. If you don't move on it, Someone will whip you from behind. Such a punishment is really terrible.
In addition, the treadmill will be directly connected to the country's water and electricity system, so that while running is punished, these people can be used to work while providing a large amount of energy, which is really two birds with one stone.
Who would have thought that the fitness method that young people like so much now was actually a form of punishment in ancient times, and the most popular thing among young people today is probably the treadmill, but in ancient times, prison cells The prisoners inside shivered when they saw the treadmill.
In addition, I would also like to mention high heels. In ancient Europe, high heels were invented for men, because in ancient Europe, all men had to learn to ride horses, and short statures When a man rides a horse, his feet cannot touch the saddle, so high heels were invented. This not only makes him look very tall and adds a lot of masculinity, but also makes it more convenient for him to stand at a minimum. It is really an invention that kills two birds with one stone.
