Yes, CK, nightmares are very à propos when Halloween time comes, with all these disguises, costumes, false and misleading appearances, etc… etc… And a great truth of life is that the older you get, the less sexy you become. You can hold on at sixteen for as long as you can if you like, but you obviously can’t do it all your life. However, let it be known that it is not the case for intelligence in most cases. If you brush away senility out of the picture to simplify the following consideration, intelligence is left unaffected by aging. It may actually be like a good camembert, getting better and better as years fly by, although there are no existing formal proofs of the preceding consideration.

To conclude, I wouldn’t worry too much about Marina. She seems to be a very intelligent person, and will surely find someone or something to do.

We don’t know the facts. The truth is most likely something between a quarter billion persons viewing one video and a quarter billion videos viewed by one person.
Let’s agree that elementary mathematics and exotic mathematics are not on the same level. BTW, I think the rule of l’Hôpital is a heuristic, and a heuristic is a fallacy in itself, although its conclusion might sometimes be true.
Zero (wich is anything divided by infinity and at the same time anything multiplicated by zero) is nullified by adding or substracting anything to it, and infinity (which is anything divided by zero and at the same time anything multiplicated by infinity) is left unchanged by adding or substracting anything to it. Heh. Zero.. Infinity.. It all depends on which one is the numerator and which one is the denominator.
Division by zero is perfectly valid in maths. It gives an infinite quantity, wich is as valid and important as the zero. Infinite only blows up a computer, not a human mind. The fallacy in the demo above is to add two \infty quantities (a+b), and claim that it gives 2x \infty, which is mathematically unacceptable, as 2x \infty = \infty. You two might be interested by the work of George Berkeley.
