I think it's just connected with that little twitch your body does when you are at the brink to fall asleep, the body belives your dead or dying, and then it tried to shock you up as a way of life-safing prossedure.
Pretty cool feature actually, but sucks when you falling asleep on the bus just to plant your foot in the man in front of you without realizing before he stands in front of you asking why the **** you kicked him. :scared:
1. Beetles taste like apples, wasps like pine nuts, and worms like fried bacon.
2. A cockroachcan live several weeks with its head cut off!
3. Human thigh bones are stronger than concrete.
4. Adolf Hitler was a vegetarian, and had only ONE testicle.
5. The average lead pencil will draw a line 35 miles long or write approximately 50,000 English words.
6. Dolphins sleep with one eye open!
7. The longest recorded flight of a chicken is 13 seconds
8. A man named Charles Osborne had the hiccups for 69 years!
9. The cigarette lighter was invented before the match
10. The longest place name still in use is:

-- a New Zealand hill.
In 1932 adolf hitler designed a car for volkswagen, in 1938 it was launched and called the Kraft durch Freude. That car was what we now know as a volkswagen beetle.
Did you know that:
It would be a waste of everyone's time to bend down and pick up a $500 note, since they've been out of circulation since 1969 as they were only used by banks and organized crime.

On the topic of Einstein:
Einstein made our current GPS positioning system possible. According to his theories of special and general relativity time is influenced by gravity and speed. As a result, time for geosynchronised orbit objects (like GPS satelites) runs faster than on the surface of the earth. Clocks in those satelites account for this difference, otherwise they would wrongly inform you of their position (by 7 meters per 12 hours).
Stellar Mass Black holes (black holes that have the mass of a couple of suns) are places in our universe you really don't want to find yourself driving your car into. The gravitational field of a black hole towards its event horizon (point of no return) is so sudden and great that you will be 'spaghettified' before you ever get to it. Basically you will get really long and really thin because of the differences in gravity between what your feet and head experience.
Supermassive Black Holes are just as deadly, but since they are so much bigger, their gravitational field is way bigger, meaning that if you fall into the event horizon, you won't be spaghettified for a while. Unfortunately what goes into a black hole probably won't come out (although that's a subject of serious debate as that presents us with a paradox), so you won't be able to tell us what the inside of the event horizon looks like.
Also, from the point of view of an outside observer looking at you while you fall into a black hole, you will turn red and slow down more and more while falling. You can see that observer, but he will turn blue and speed up due to gravitational time dilation (same as the GPS sats). For you the whole deal is over pretty quick as time runs at normal speed for you, but for the outside observer it will take forever for you to disappear into the event horizon.
The average photon (light particle) takes around 8 minutes to travel the 150 million km (93 million miles) from the sun to earth. However, the photon was born in the core of the sun where the density is so big that it can only travel a short bit before being absorbed by another particle. It takes the average photon anywhere from 12000 to 80000 years to travel the 700000 km from the sun's core to the suns surface.
Also, you cannot physically measure the path a single photon takes. If you do that it will invariably turn from a particle into a wave and take all possible paths simultaneously.
