Why do older people forget things more frequently than younger people?
It's called age. As we get older, all parts of our bodies weaken, including memory. Plus there is what is called, 'Alzheimer's disease'. Every part of a human body weakens and dies, the memory part of the brain is a part that goes fast in some. It's called life!
When a human is born his brain is "empty" and is continously filled with a lot of information. By experiencing and repeating things synapses connect to specific brain regions. The more information of one kind is coming to the brain more and more synapses will be connected. Slowly the Brain is getting a specialist for certain tasks. That's for example the reason why People who play the Piano since they were Children are better in playing than people who startet later.
Most People are constantly giving order to their lifes and many days are just like the day before. So the Brain is specializing every day a bit more and not capable of processing any new information coming towards it.
Persons who suffer from 'Alzheimers disease' mostly forget what they did only minutes ago or in bad cases Years while they can perfectly remember what they did when they were young.

Poe's poem, "To F___s S. O___d" (To Frances S. Osgood) was originally typeset with em-dashes to disguise some of the letters in her name, but the WikiAnswers question field won't accept most punctuation marks. Unfortunately, the title won't reproduce properly in the answer box, either, but it originally looked something like this: "To F--s S. O--d" (those hyphens should be em-dashes, which are twice as long).
The Grandfather Paradox
This paradox is often used to prove that time travel can't exist. Another "proof" is that we've never been visited by people from the future, which goes to show that time travel will "never" be possible. By changing the past, you change the future in which you are able to travel into the past.
In science fiction treatments of this subject, there are some typical resolutions :
- The killer would still be alive, but unable to leave the past because the time stream was altered.
- When the person changes the past, he (she) returns to an altered future where he never existed, or where time travel never existed.
- The time traveler returns to an alternate future, where he is a different person, having had one different biological parent/grandparent.
- For some reason, the murder never happens. They miss, or run out of bullets, or kill the wrong person (protection of the timeline). In at least one instance, changing the past crashes the time travel method and throws the person back to the future.
Time Loop - when she "did" kill her grandmother, she wouldn't have been born, so then she wouldn't have killed her, so she WOULD have been born, so did kill her, and was erased out of existence, but then was born (and so forth).
Analogy to Self-Murder - That's just like killing yourself, so it would have to be an alternate universe, or one where she was born as another person in another family.

Can you make nine out of l l l l l l by only adding 5 lines?
You need to add the lines in such a way that they SPELL "nine," not that they add up to make a total of nine lines. It's a trick question. Simply add a diagonal line from top left to bottom right to the first two vertical lines and you have the letter "N." Then leave the third vertical alone as it is already the letter "I." Then do the same thing you did to the first two lines to the fourth and fifth lines for the second "N." Finally, add three horizontal lines to the last vertical line to make the letter "E" and, shazam, you have N-I-N-E.
How do you fold a piece of paper into tenths?

For a square:
Fold the paper in half twice
A____D
|..:..|
|_:_|
B C
Then, fold the bottom right corner up along the line formed by the midpoint of line CD and corner B. Corner C now lies on the a line dividing the paper into 2/5( the right of the square) and 3/5 (the left of the square). Now simply fold along that line, and you have that proportion. The rest is straightforward. Simply divide the 2/5 in four and use that size to divide the rest into tenths. forgive the other guy for iving you such a stupid answer.
