What are some daily things that we are unaware of?

1. Stickers on fruit: The stickers mark the country and producer of the fruit, but it’s the numbers that are the important aspect. If there are 4 digits and the first number is 4, then it means the fruit is sprayed with pesticides. If there are 5 digits and the first number is 9, then the fruit has grown organically, and if there are 5 digits with the first number being 8, then the fruit has been genetically modified.


2. Doughnut hole: In the past, it was difficult to get the edges and the middle of the pie equally baked. So they came up with the ingenious idea of using this shape to ensure equal baking on all sides.


3. The original reason for sunglasses: today it’s obviously to protect us from the sun’s rays. But the original purpose was to protect Arctic people from the dazzling rays of snow. And in 12th century China, they became particularly widespread among judges in order to hide their true feelings from witnesses.


4. Margins on paper: the original purpose was not for extra notes on the side. In the past mice and rats often gnawed on the paper, so in order for them not eat away the information, people started to leave spaces on the sides.


5. Holes in padlocks: People usually buy a new lock when their old one doesn’t work due to rain. However, the purpose of the hole is to put in oil - once done, the lock should be able to open with no difficulty.

WOW Very informative since I did not know any of that. I immediately went to the kitchen to check on the fruits: Apple USA 4130, Lemon USA 4053, Avocado Mexico 4225. All sprayed with pesticides. Rule of thumb for me: If it is not to be pealed, wash with soap and water before eating, especially apples. Thank you for educating us Quiz Folks. You're back in my good graces.

This isn't really in the same category but if you light a candle close to where you're peeling onions, your eyes won't burn. : )

Some interesting things that I did not know. I find putting oil in the little holes on a padlock the most useful. I had always wondered what those were for. The numbers on the fruit were very useful. I had no idea! Thanks for some interesting & useful info.
