Few curiosities that always made me think why

Why is match box called “safety matchbox” even it is fire generator?

John from Cisco certified Network Associate answers in Quora, The safety match was invented in 1844 in Sweden, by Gustaf Eric Pasch, improved on by Johan Edvard Lundström, and prevented unintentional combustion by separating the reactive ingredients between the match head and the striking surface. Pennsylvania attorney Joshua Pusey invented the matchbook, containing 50 matches and a striking surface on the inside of the cover. The Match Company bought Pusey’s patent, and improved the safety of the design by placing the striking surface on the outside.

I understood, earlier there were “Strike Anywhere” type of matches, which were truly dangerous and had risk of catching fire accidentally due to friction.

Safety matches are safe in this term that they need intentional strike to ignite.

Why is next day of Christmas called Boxing Day?

In early seventies, rich people in England gifted their servants as take away to their home with a “Christmas Box” which contained used/new clothes, leftover food, used toys and other presents. It happened in next day of Christmas day because servants provided good service throughout the year and waited their masters for Christmas night.

People call “Black Friday” yet shop more, why it is not called blue Friday?

My first thought when I heard about “Black Friday Shopping” was like, some days become black day because something bad happened on that day. Like in Nepal we say February 1st Black day in history because king coop the power of people. In similar understanding Black Friday had to be a day, at least people don’t fell like celebrating, isn’t it ? But I was wrong; I got curios and searched in internet.
Wikipedia says “Black Friday is the day following Thanksgiving Day in the United States (the fourth Thursday of November). Since 1952, it has been regarded as the beginning of the Christmas shopping season in the U.S., and most major retailers open very early (and more recently during overnight hours) and offer promotional sales. Black Friday in a shopping context suggests that the term originated in Philadelphia, where it was used to describe by the police officers for the terrible traffic conditions that would occur on the day after Thanksgiving.


While another school of thought is, this day retailers made big profits which means this day represented the point in the year when retailers begin to turn a profit, thus going from being “in the red” (red ink for loss ) to being “in the black” (Black ink for profit)

Why Punjabis (Shikhs) do not cut hair?

According to Harmandeep Kaur in Qora answers ,Shikhs believe hair is gift from God, therefore why should anyone give it away by cutting it? Hair is one of the five articles of faith for Sikhs. Sikhs live the way God made humans and never cut their hair. For Sikhs hair is the symbol of love for God and the respect for everything he has given. The way God made us is the most beautiful of all.


From the scientific point of view, keeping hair is practical because hair has many functions. It traps an insulating layer of still air just outside the skin, and thereby keeping the head cool in summer and warm in winters. Furthermore, hair absorbs harmful ultra violet radiations from the sun and reduces skin cancer. In addition, hair follicles can make androgenic hormones. Axillary hair provides larger surface area for evaporation of sweat. Although Sikhs do not need scientific explanations to keep hair, it is important to note that scientific explanations do indeed exist.
