Things close...With a past you may never know.

1. Chainsaws used to be a delivery device:

Before becoming a brutal logging tool in horror movies, the chainsaw was invented by two Scottish surgeons (in the 1780s) to use it to "saw a woman's pelvis while giving birth to a difficult baby (Symphysiotomy) to help widen the vagina. It was designed to rotate by hand and have small sawtooth teeth, which of course caused enormous pain before doping.

2. Treadmills are prisoner torture machines:

In the 19th century, the treadmill was not for health, but it was a punishment tool in British prisons. Prisoners had to walk on a giant turbine for hours a day to grind grain or pump water. If anyone stopped walking, it would fall injured. It was a hard-working punishment to curl the habit, until the law repealed it because it was too cruel, before it was later converted into an exercise machine.

3. High Heels starting from Warrior Boys:

Originally, high heels were designed for the "Persian cavalry." The higher heels helped the lock foot to firmly stick to the stirrup while standing archery on horseback. Later, European aristocrats put it on to show its position and masculinity (Masculinity). The richer the heels and reds looked, until this fashion gradually transitioned into women in the latter, and men eventually quit wearing it.

4. Post-it is a failure that becomes money:

Dr. Spencer Silver tried to invent a huge adhesive for use in the aircraft industry, but he made a mistake, a glue that was "not tight" and very easily peeled, and he kept this failed work for six years until his colleagues came up with the idea of making a hymn paper in the church that would not fall, becoming an innovation that changed the working world forever.

5. Coke (Coca-Cola) used to actually contain cocaine:

In its early beginnings (late 19th century), the drink was sold as a "neuroscient" and contained a mixture of coca leaf extract (which contained a certain amount of pure cocaine) to help relieve headaches and fatigue, before this type of substance was cut off in 1903 and replaced instead with caffeine from other plants, but kept the same brand name for trade.
