Why Do Women Tolerate High Heels?

Why do women wear high heels, according to the daily mail of Britain?

Why should soft drinks be kept in a round container while a milk carton is rectangular?

Why did the pilots of the kamikaze team wear helmets?

Robert.H. Frank, an economist at Cornell University, explains some strange things that we encounter in our daily life from an economist's point of view.

Why are women willing to tolerate high-heeled shoes?

High heels are very uncomfortable and will make walking more difficult.

Wearing high-heeled shoes for a long time can also cause damage to the feet, knees and back.

But why do women like to wear them all the time?

The simple answer to this seems to be that women wearing high heels are more attractive to others.

In the sense and sensibility, Jan Austin describes the heroine Eleanor Dashwood as a "gentle, virtuous, regular, beautiful girl."

But Austen described Dashwood's sister as a "romantic and passionate person".

Her appearance (others think her appearance is not as dignified as her elder sister, and her height is slightly superior to her elder sister) is even more striking.

In addition to making women look taller, high-heeled shoes also force the back to be arc-shaped, urges women to raise their chest and buttocks, thus highlighting the outward appearance of women.

Caroline Cox, a fashionable historian, wrote, "men like the exaggeration of women's appearance."

However, the problem is that if all women wear high heels, this advantage is likely to disappear.

After all, height is a relative phenomenon.

Taller people, or at least not a few inches shorter than others, are more dominant than others.

But when everyone puts on high heels and makes himself look a few inches taller than the original, the relative height difference has no effect. No one looks taller. Everyone is like wearing flat shoes.

If women can decide what shoes to wear together, they will agree not to wear high heels.

But because anyone can get the advantage from wearing high heels, this consensus is hard to achieve.

Why do not more people wear cingled shoes?

George de Masdeo, a Swiss inventor, learned how to tie shoelaces until 1955 when he obtained the patent of the buckles.

After he obtained the patent, the sticky tape replaced the zippers, hooks, shoelaces and other methods to fasten things.

As a way of fastening shoes, the strap is obviously more advantageous than shoelace.

For example, shoelace loose and sometimes tripping people.

Although there seems to be a short time when it seems that the buckle will squeeze the shoelaces out of the market, the number of adults who wear sticky shoes is still very small.

Why do shoelaces survive?

From the very beginning, the most popular application of sticky tape in the footwear industry is to help children, the elderly and the disadvantaged.

Sticky tape is popular in children's shoes because many young children have yet to learn how to tie their shoelaces.

In the elderly, the popularity of buckles is due to medical reasons.

For example, some elderly people can hardly bend down to tie their shoelaces, while some elderly people are difficult to tie their shoes because of their arthritis.

As a result, in the public mind, sticky tape has been associated with mobility and weakness.

Even in many ways, the shoes that use the buckles are more durable than shoes with shoelaces, but shoelaces are unlikely to disappear in the near future.

Why do some petrol tanks cover the driver's side?

When you rent a car, the most frustrating thing is that when you pull the gasoline tank lid like your own car, you find the fuel tank on the other side of the car.

A car manufacturer can easily solve this problem by putting petrol tanks on the same side of the car all the time.

But why do they not do so?

In some countries, vehicles generally drive on the right side of the road, such as the United States.

When crossing the head-on traffic, turning right is easier than turning left.

If the fuel tank is always placed on the driver's side.

The driver can only stop on the right side of the fuel pump before refueling.

In this case, when there are many refueling vehicles, all the space on the right side of the pump is full of vehicles waiting for refueling, but the left side is empty.

The gasoline tank covers of different vehicles are located on different sides of the vehicle, which means that some vehicles can be refueling on the left side of the fuel pump.

Drivers are more likely to queue up in order.

Why is whale extinct and chicken is not?

For one year, there is no living example to condemn the danger of extermination caused by international hunting to many large marine mammals.

At the moment, however, I do not know any examples of advice that we should save chickens.

Why is that?

The short answer is that chicken has never been an endangered species.

But this further deepens people's doubts about why a species will become extinct and the other will not.

The number of whale is declining because no one owns whales.

They swim in the international ocean. Several countries refuse to abide by international treaties, and do not want to protect them.

Whaling people in Japan and Norway know that their current activities are threatening whales and their own livelihoods.

But these whales know that if they do not catch whales, others will catch them.

Most of the chickens in the world have their own owners.

If you kill one of your chickens today, you will have fewer chickens tomorrow.

If a chicken farm is your way of making a living, you must ensure that the number of chickens sold in the market is balanced with the number of chickens hatched.

Chicken and whale have economic value.

People like to protect the property rights of chicken, rather than the fact of whale, can explain why the former is numerous, and the latter is facing the danger of extinction.

Why is DVD's box bigger than CD?

CD box width 148 mm, 125 mm high.

By comparison, DVD's box is 135 millimeters wide and 191 millimeters.

Why do manufacturers use different boxes to hold the same size disks?

Relevant personnel have found this different root in history.

Before the advent of digital CD, most of the music records sold were made of vinyl resin and placed in a 3.2 inch tight fitting jacket.

The thickness of the vinyl disk box is enough to hold two CD, separated by a spacer in the middle.

The width of CD containers is less than half the size of the record covers that they are replacing. This avoids retailers from stealing and changing profits and seeking huge profits.

The size of the DVD box seems to be driven by reality.

Before DVD became popular, most video rental shops used video cassette formats to record video cassette, which was placed in a suitable box with a width of 135 millimeters and a height of 191 millimeters.

These videos are often released on the shelves.

DVD manufacturers have made the same size boxes, so that they can use existing shelves to sell their new DVD, prompting consumers to gradually shift their attention to this new disk type.

The size of the DVD box is the same as the size of the tape cassette of the home video cassette tape. It also makes the product more attractive to the consumers because the original DVD is stored on the shelf of the home video recording system.

Why did the kamikaze wear helmets?

After the Japanese military suffered major setbacks in 1944, the Chinese army launched a kamikaze suicidal attack. In this activity, the pilots tried to collide with the US warships with their planes.

These planes are loaded with explosives, so for these pilots, the impact almost certainly means death.

Why do these pilots wear helmets?

One reason is that in some instances, the kamikaze pilots survived the mission.

Another reason is that aircraft often experience severe turbulence before reaching the target. Under such circumstances, Japanese military commanders obviously have reason to provide adequate protection for their pilots.

Perhaps one of the more important reasons is that the helmet has become a symbol of a pilot.

The kamikaze pilots are all pilots and all pilots wear helmets.

But the most farfetched explanation of why the kamikaze pilots wear helmets is that they do not want the enemy to see that these pilots attempt suicide attacks at a glance.

Their task is to take any means to destroy their goals.

But they hope that these pilots will be able to return safely after their mission, even if that expectation is impossible.

Why do men and women wear buttons differently?

In western countries, buttons on women's clothing are buckled to the left, while men's clothing buttons are buckled to the right.

Why is that?

We are hardly surprised that garment manufacturers support the uniform standard of selling different styles of clothing to any particular group.

However, a standard adopted by women is just opposite to that of men, which is really puzzling.

If this standard is arbitrary, it will also be said in the past.

But men's standards seem to have some meaning for women's standards.

About 90% of the world's population uses their right hands, and right-handed people button their buttons from the right.

Why do women button their buttons on the left?

Historical events may help us explain this problem.

In seventeenth Century, when buttons had just appeared, they only appeared on the coat of the rich.

At that time, the rich men dressed themselves, while the women had their servants dressed for them.

Is it possible for women's shirt buttons to be buckled from the left to make it easier for most right-handed servants to dress for them?

Men's buttons are fasten from the right side, not only because most men wear their own clothes, but also because men pull the sword from their left buttocks with their right hands, which makes it more difficult to affect the appearance of the shirts.

Now, basically, there are no women who dress their servants for themselves. Why is it still a standard for women to button buttons from the left?

In economics, a defined standard will be resistant to change.

When all blouses are buttoned from the left side, any garment manufacturer who launches shirts from the right is very risky.

After all, women have been accustomed to button their shirts from the left during their growing up. In order to change this habit, women have to develop new habits and skills.

In addition to these practical difficulties, some women will find that wearing buttons from the right button in public places is not good for society because people will think they are wearing men's shirts.
