Typing keyboards used to be arranged alphabetically. Have you ever wondered why keyboards aren’t arranged by the ABCs compared to the QWERTY keys we know now? You’d be surprised to know the uniform QWERTY keys we use were chosen at random. Before PCs and laptops, the typewriter was man’s first typing experience. The earliest typewriters had alphabetic keys, but people typed so fast that the mechanical arms got jammed and tangled up. To solve this, the keys were randomly positioned to slow down typing and prevent key jamming.
The foil seals on medicine bottles were placed due to poisoning incidents. The Tylenol poisonings of 1982 were a widespread crisis that involved U.S. consumers dying or falling ill from Tylenol. It was later found that the bottles had been laced with potassium cyanide.

Instead, they made their informal policy formal to prevent it from happening again!
Arizona fines drivers under their unique “Stupid Motorist Law.” This law addresses something which Arizona is all too familiar with – flash floods and stupid drivers.

A wall of trees is being planted across Africa to help prevent desertification. The Great Green Wall of the Sahara and the Sahel is Africa’s leading attempt to help mitigate the effects of desertification. The initiative also aims to transform the lives of millions of people living along the edge of the Sahara Desert. Unsurprisingly, planting trees at the edge of a desert is difficult. Despite having planted more than 5.5 billion seedlings in Ethiopia alone, only four per cent of the project had been completed by the end of 2020.
