There are very few people who can exude a natural demeanor when they are actually forcing it. Basically, they are trying to physically fake what they think they look like when they aren't paying attention to a specific stimuli. It's easy to spot because people aren't good at this and it's apparent in their face, body, and just how they carry themselves in general.

It's because the local station is list a second late in starting the local commercial.

The network will have certain commercial spots that are for local affiliates/cable companies to air ads that they sell. But, just in case the local station doesn't have anything for that, the network will have a commercial running.

When it works smoothly, you don't see it, because the local ad completely covers up the national ad. But if the local channel is a little late in starting the ad, you'll see just a bit of the national ad first.

There is a water line behind the fridge that is tied into your house water supply lines. It's usually a clear flexible line that allows you to pull the fridge out from the wall. The same water that comes out of your taps goes to the fridge.

Because its fucking awesome, that's why!

You can drink tea for breakfast before you eat, you can have a cup with your toast. When you get into work you can have another cup, another when you have your first tea break, another cup at about 11. Its lunch time so better make a brew, going for a smoke? Bring some tea, mid afternoon tea break, cup if tea when you get home from work, again with dinner, another for supper and finally one for bed.

Tea is a way of life.

Cyanoacrylates (Superglue) react with water vapor in the air to polymerize and harden. The inside of the bottle is dry, so nothing happens until you take the cap off.

Elmer's (polyvinyl acetate emulsion) is the opposite and hardens when it loses water.

Exposure to the air allows the chemicals that keep the glue liquid to evaporate and the glue to harden. When it's in the bottle it's a sealed environment so the chemicals have nowhere to to and so it stays liquid.

Credit score determines your trustworthiness that you have the ability to pay back the loan. Two biggest things that people purchase is car and house. Credit score determines 1) if the bank even gives you the loan 2) how much they charge you for it.

"O Levels" no longer exist, they were replaced by GCSE's. GCSE's are the minimum compulsory level of education we have to study for. We take the exams at age 16 and we can leave education altogether after that, if we wish.

If we wish to continue with academic education (as opposed to work or more vocational education, which also becomes an option at this age), we pursue "A levels" for a further two years, until age 18.

Most people generally study for around 8 - 12 subjects at GCSE, and around 3 - 4 subjects at A Level. Hence, A level is much more specialised, and often people chose specific subjects in order to lead to a particular university major. (For example, if you wished to study medicine at university, you would have had to have studied science subjects at A Level)

Also, certain subjects are compulsory at GCSE - everybody has to take maths, English and some science, for example. At A level we get absolutely free choice to study whichever subjects we want.

EDIT: I should add that "O Level" used to stand for "Ordinary Level (of education)" and "A Level" for "Advanced Level".

Because it gives you a fundamental understanding of the underlying principle. Sure, you could just measure the hypotenuse of a right triangle, or punch the data into a calculator, but by memorizing and truly understanding the Pythagorean theorem, you gain a deeper understanding of math and geometry. It's like memorizing how our government works, instead of just looking up in a book who to bring your concerns to whenever things go poorly.
