If drinking and driving is forbidden why do bars have parking lots?

Well, bars also serve non-alcoholic beverages. When a group of people visits a bar there often is a designated driver who needs a place to park the car. Also, the bar’s staff has to park somewhere.
What is also important is that many countries have a drunk driving limit, so driving under the influence of alcohol is permitted.
So, there are plenty of reasons why bars need to have a parking lot.

If nothing sticks to Teflon, how does Teflon stick to the pan?

Polytetrafluoroethylene (PTFE), better known as Teflon, is a partially crystalline polymer consisting of fluorine and carbon. It was accidentally discovered in 1938 by chemist Roy Plunkett who was searching for refrigerants and experimented with Tetrafluoroethylene (TFE).The pan’s surface is mechanically roughened by sandblasting which causes the surface to become uneven. The PTFE is then applied under pressure, sticking to the pan’s uneven surface. However, the PTFE’s surface is smooth and therefore the food doesn’t stick to it.

What’s the name of the plastic ends of shoelaces?

The hard ends of shoe laces are called aglets deriving from the Old French word aguilette, the diminutive of aguille (needle). Aguille in turn comes from the Latin word acus (needle).

If a shop is open 24/7 all year, why does it need door locks?

Firstly, I have never seen a shop door without locks.
Anyways, I think there are various reasons for these shops to have locks on their doors. The shop can be closed due to its owners being on vacation or ill. On the other hand shops need repairs.
However, some shops are open 24/7 but still have their doors locked at certain times; e.g. gas stations. Their doors are locked at (I think) 10 p.m. so customers have to use the night desk to buy goods or pay for gas. This is done for reasons of security as gas stations are often robbed at night. So, there are enough reasons for these shops to have locks on their doors.

Why do Kamikaze pilots wear helmets?

The actual name of the Japanese unit flying suicide attacks was Tokubetsu Kōgekitai, meaning “Special Attack Unit”. In Japanese Kamikaze actually means “divine winds” and is known since the 13th century when the Mongols tried to invade Japan. Although the Mongols could land on the island of Kyūshū their fleets were destroyed twice by typhoons. These typhoons are said to have killed 10,000 and 100,000 men respectively.
Concerning the Kamikaze pilots I searched the internet for images and it struck me that they do not wear helmets. The pilots I saw wore aviator caps made of leather. Anyway, let’s count these caps as helmets. Still, the question remains why they wore helmets if they were going to die?
I read an extract from a Kamikaze pilots’ manual saying that the pilots should remain in good health and good spirit. So wearing these caps might have had some psychological effect. They felt safe during the flight and the cap made their uniforms complete. Thus, the pilots might have felt complete keeping them in good health and good spirit.

Why is there no cat food with mice-flavor?

Cats love mice to bits. Still, you won’t find any mice-flavored cat food no matter how many supermarkets you go to. Why is that so?
The production of cat food is closely related to, if not depending on, human food. It consists of meat scraps and variety meat of human food production. Since people don no eat mice there is little chance of producing mice-flavored cat food.

When a schizophrenic threatens to commit suicide is he taking a hostage at the same time?

No, he is not taking a hostage. It is a common misbelieve to think that a schizophrenic “consists” of several personalities. The symptoms of schizophrenia are rather delusions and paranoia.
Actually, the question refers to people suffering from Multiple Personality Disorder (MPD). People with MPD are controlled by at least two personalities, e.g. Dr. Jekyll and Mr. Hyde. Applying the same question to an MPD patient is still interesting although I can only answer it according to German criminal law. There it states that taking a hostage means to abduct or to seize another person in order to hurt the latter and/or a third party. Consequently, a hostage situation has to involve at least two different people: the hostage and the hostage taker. Consequently, one person cannot be both at the same time even when suffering from MPD.

If you tell people there are 400 trillion stars in the sky they believe you. But why do they have to touch a bench if you tell them it’s freshly painted?

400 trillion is a number we cannot grasp and no one can actually verify the amount of stars in the sky. So people tend to believe things they cannot argue about. It was – and still is – the same with me and math. Tell me everything about curve sketching and I’d say amen to that because I’m neither keen nor able to prove you wrong.
However, tell me koalas love smoking eucalyptus reefers and I’d never go to a zoo without a lighter anymore –just in case.
Everyone can verify if a bench is really freshly painted and people tend to verify their belief by touching things. Studies showed that people are more likely to buy things they could touch beforehand.
So maybe it’s because the stars are literally out of reach while the bench isn’t.
