pneumonoultramicroscopicsilicovolcanoconiosis has 45 letters in it and its some disease similar to black lung disease. You get it somehow from being around volcanoes (too long, maybe, or breathing too much volcano dust), hence pneumonoultramicroscopicsilicovolcanoconiosis

coal miners - black lung disease.
guys around volcanoes - pneumonoultramicroscopicsilicovolcanoconiosis. Sorry if this wasn't clear.
For some reason, everyone thinks that pneumonoultramicroscopicsilicovolcanoconiosis is the same as black lung disease when its only quite similar.

Saying that, looking at the name, it does appear that you could get this disease from other places too. Pneumonoultramicroscopicsilicovolcanoconiosis suggests that the disease is caused by inhaling too many ultra-fine particles of silicon dioxide or other silicon-based minerals. I suppose that you could also get this if you lived next to a sandstone quarry or something like that (Sand is mostly silicon dioxide, if I'm not wrong).

Multiplying two consecutive integers and adding 17 will always result in a prime number.

1x2+17=19
2x3+17=23
3x4+17=29
4x5+17=37
5x6+17=47
etc.

Multiplying two consecutive integers that are greater than 1 will always result in a non-prime. Especially if you add 16 to them.

Ok - multiplying an integer by 23 and adding 23 will always result in a non-prime.

And the answer to RoboBob3000's question, at least as far as I am concerned - people who are looking for stuff to do to avoid work.

pi ~= e for large values of e.

When rounding numbers to integers, the basic rule is within .5 of a value. So 3.5 can round to 3, because it's only .5 more than 3, but it can also round to 4, because it's only .5 less than 4. pi is roughly 3.14159, and e is roughly 2.81828, and they are within .5 of each other, so they are roughly equal.

Similarly, pi ~= 4 for large values of pi and small values of 4.

Being a big Coca-Cola fan, I have to add something on it. (Sorry in advance to all Pepsi fans)

Did you know...

-Coca-Cola was originally green.
-Coca-Cola was invented by a pharmacist on May 8, 1886.
-There are nearly 10,450 soft drinks from The Coca-Cola Company consumed every second of every day.
-Although 'Coca-Cola' is enjoyed ice-cold around the world, in Hong Kong it is sometimes served hot as a remedy for colds.

All of the facts here except the first (Which I had in my memory) were found here, a very good site for all you Coca-Cola fans.

Well, in reality, each of them are bad for you, they are just bad in different ways.

Fries = Fat, Grease
Coke = Sugar, Caffeine

Edit: Duh. French Fries also equal potatoes.

Coke also equals very concentrated carbonic acid (H2CO3) at around pH 2-3. It's very bad for your digestive tract if consumed in high quantities.

Ack! That'll keep me away from the stuff for a while. And just a quick question - What is considered "High Quantities"? Would it be somewhere around 1-2 litres a day, higher, or lower?

That's sort of true, but very misleading.

First, All carbonated drinks contain carbonic acid, not just coke.

Second, carbonic acid is a weak acid (ph around 3). The gastric acid in our stomach has a PH of around 1; our digestive tracks can handle any acid weaker than that without trouble. Fresh orange or lemon juice is considerably more acidic than coke, yet no one goes around saying it's harmful to the digestive tract.

Note that I'm not saying that Coke is healthy - far from it. But the sugar and caffeine are the real health risks - the acidy, while much more scary sounding, is really a non-issue.

If you leave a tooth in coke for enough time (several days at least, far more than the several hours folklore ascribes to it), it will melt. Given the very short amount of time your tooth actually comes in contact with coke when you drink it (a few seconds at most per liter), it causes less damage to the tooth than the normal wear from biting into stuff whenever you eat does.

On the other hand, coke will leave a sugary deposit on your teeth, which, unless brushed off relatively quickly, will lead to bacterial growth and eventual tooth decay, just like any other heavily sugary substance. So, here too, the acidic properties of coke are far less important than its sugar content.

Correct. So beware that seemingly docile can of carbonated drink!

Second, carbonic acid is a weak acid (ph around 3). The gastric acid in our stomach has a PH of around 1; our digestive tracks can handle any acid weaker than that without trouble.

Actually, that's not entirely true, I don't think. Carbonic acid is weak (It only dissociates partially), but in a can of carbonated drink, it's very highly concentrated, since they force more CO2 into it than can be dissolved into it at atmospheric pressure (hence the fizziness), thus decreasing the pH of it to about 2-3. Stomach acid has a pH of around 1-2, so you are correct to say that this acid will not damage the lining of your stomach on contact, but since there is more acid in your stomach, it makes it much harder to fully neutralise it all when it passes into your small intestine.

Fresh orange or lemon juice is considerably more acidic than coke, yet no one goes around saying it's harmful to the digestive tract.

If you drank fresh lemon juice in large quantities of around 1-2 litres a day, I'm pretty sure that it certainly won't be very good for your digestive tract after a while.
