The bad news is, I shrink an inch every day also!

Don't believe me? Try this: before you go to sleep tonight, stand against a wall and measure how tall you are using a pencil. When you wake up the next day after a FULL NIGHT'S sleep, measure your height again next to last night's measurement. You will see you grew by half an inch to an inch, guaranteed!

The reason for this? In a word: Gravity!

People are taller after a long sleep 'cause the pads between their joints, especially the joints of the spine, are able to recover their shape. Pressure caused by our weight acting on the cushioning intervertebral discs between our vertebrae flattens them slightly during the day and fluid is squeezed from the discs during the day, but is reabsorbed during the night.

Basically, gravity shrinks you down about an inch vertically every day; you "unshrink" during the night back to your actual height!

So yes, you are actually taller than you said you were on your driver's license!!!

Mention the planets of the solar system which are impossible to be seen at midnight sky? ( whether by naked eye, by telescope or by any other means ). You look into the night sky preferably around midnight and can never see these planets, mention the names.

It would be great if we start asking some quiz here in addition to the discussion to make it more interesting, am I right? it may improve our universe/ galaxy knowledge as well.

do you all agree with me?

I've heard that blue eyes are the most recessive eye color, but I was wondering if it was really green. Green is a lighter color, since yellow + blue make green. Does anyone know?

The really weird thing about it is that my mom has blue eyes, but my aunt (her sister) has green eyes. They have the same parents too.

I saw on the news a brief thing about new photos of bigfoot caught by real researchers. They left the camera in a place where there were sightings. It was motion triggered and they got a picture or two but i just cant seem to locate it. Thanks for any help you can give. I know this is a crazy request but I am curiouse due to an incounter of my own that is unexplained and NO IT WAS NOT A BEAR! I have had close contact witha bear and it was most definatly NOT A BEAR. If you could have smelled the smell and heard the scream of it you would understand. AND NOT I AM NOT ON DRUG AND NO I DO NOT DRINK.

Asking because i keep hearing that most Americans of the South are of Scottish and Scotch-Irish descent yet when you look at the ancestry figures for the Southern states English Americans greatly outnumber those who put Scottish, Scotch-Irish or American as their ancestry.
