What Happens To Your Body If You Drink A Coke Right Now?

In The First 10 minutes: 10 teaspoons of sugar hit your system. (100% of your recommended daily intake.) You don’t immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavor allowing you to keep it down.
20 minutes: Your blood sugar spikes, causing an insulin burst. Your liver responds to this by turning any sugar it can get it’s hands on into fat. (There’s plenty of that at this particular moment)
40 minutes: Caffeine absorption is complete. Your pupils dialate, your blood pressure rises, as a response your livers dumps more sugar into your bloodstream. The adenosine receptors in your brain are now blocked preventing drowsiness.
45 minutes: Your body ups your dopamine production stimulating the pleasure centers of your brain. This is physically the same way heroin works, by the way.
>60 minutes: The phosphoric acid binds calcium, magnesium and zinc in your lower intestine, providing a further boost in metabolism. This is compounded by high doses of sugar and artificial sweeteners also increasing the urinary excretion of calcium.
>60 Minutes: The caffeine’s diuretic properties come into play. (It makes you have to pee.) It is now assured that you’ll evacuate the bonded calcium, magnesium and zinc that was headed to your bones as well as sodium, electrolyte and water.
>60 minutes: As the rave inside of you dies down you’ll start to have a sugar crash. You may become irritable and/or sluggish. You’ve also now, literally, pissed away all the water that was in the Coke. But not before infusing it with valuable nutrients your body could have used for things like even having the ability to hydrate your system or build strong bones and teeth.

Right Brain vs Left Brain test

clipper's remarks: I can only see her moving clockwise!

Clip Source: www.news.com.au

THE Right Brain vs Left Brain test ... do you see the dancer turning clockwise or anti-clockwise?

If clockwise, then you use more of the right side of the brain and vice versa.

Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.

LEFT BRAIN FUNCTIONS
uses logic
detail oriented
facts rule
words and language
present and past
math and science
can comprehend
knowing
acknowledges
order/pattern perception
knows object name
reality based
forms strategies
practical
safe

RIGHT BRAIN FUNCTIONS
uses feeling
"big picture" oriented
imagination rules
symbols and images
present and future
philosophy & religion
can "get it" (i.e. meaning)
believes
appreciates
spatial perception
knows object function

70 Ways to Better Brain Power

70 Ways to Increase Your Brain Power

1. Breath deep. More air in means more oxygen in the blood and therefore in the brain. Breath through your nose and you'll notice that you use your diaphragm more, drawing air deeper into your lungs. Several deep breaths can also help to relax you, which is conducive to clearer thinking.

2. Meditate. A simple meditation you can do right now is just closing your eyes and paying attention to your breath. Tensing up your muscles and then relaxing them to start may help. When your mind wanders, just bring your attention back to your breath. Five or ten minutes of this will usually relax you, clear your mind, and leave you more ready for any mental task. For more on meditation, you can visit http://www.TheMeditationSite.com.

3. Sit up straight. Posture affects your thinking process. Prove it to yourself by doing math in your head while slouching, looking at the floor and letting your mouth hang open. Then do the mental math while sitting up straight, keeping your mouth closed and looking forward or slightly upwards. You'll notice that it's easier to think with the latter posture.

4. Phosphotidyl Serine (PS). This supplement has been shown in clinical studies to increase lucidity and rate of learning. It activates cell-to-cell communication, helps regulate cell growth, improves the functioning of the special receptors found on cells, and prepares cells for activity. In other words, it can help your brain power. It's also thought to reverse memory decline. Phosphatidylserine has no known adverse side effects.

5.Vinpocetine. This extract, derived from an alkaloid found in the Periwinkle plant, is used as a cerebral vasodilator. It increases blood flow to the brain, which improves its oxygenation and thereby increases mental alertness and acuity. Research suggests it may also be the most powerful memory enhancer available to date.

9 Brain Quirks You Didn't Realise You Had

Wed, 11 Jul 2007 22:59:58 GMT

Clip Source: www.lifehack.org

1) Your short-term memory has a max capacity of seven.

Humans have three forms of memory: sensory, long-term and short-term. Long-term memory is like hard-drive space, while short-term memory works like a very small RAM. This short-term memory can hold only about five to nine (average is seven) items at a time.

2) Chartreuse is the most visible color.

Your eyes have receptors for blue, green and red. Being in the middle, yellow-green triggers the most of these receptors to fire

3) Your subconscious is smarter than you are.

Or at least more powerful

4) You have two nervous systems.

One set controls excitation and the other controls inhibition

5) Your brain is awful at probability.

6) Your memory isn’t great either.

people are highly likely to misremember past events

it is incredibly easy to suggest a memory that never happened

7) You can perceive depth with one eye.

8 ) Long-term memory shuts down during sleep.

9) You have an instant playback feature.

If you stare at the blinking pink dots, you will see only one color, pink.
If you look at the the + in the center, you will see a circle of pink dots and a rotating green dot.

Now, stare at the + without moving your eyes.
The pink dots will disappear and you will see only a rotating green dot.
It's amazing how our brain works. There really is no green dot and
the pink ones don't really disappear. This is proof that we don't always see what we think we see.

7 Thinking Errors You Probably Make

clipper's remarks: Common thinking errors explained, each backed by a scientific study. Food for thought!

Clip Source: www.lifehack.org

The brain isn’t a flawless piece of machinery. Although it is powerful and comes in an easy to carry container, it has it’s weaknesses. A field in psychology which studies these errors, known as biases. Although you can’t upgrade your mental hardware, noticing these biases can clue you into possible mistakes

The entire domain of the scientific method has largely been an effort to overcome the natural inclination towards bias in reasoning

common thinking errors:

1) Confirmation Bias

tendency to seek information to prove, rather than disprove our theories

2) Hindsight Bias

see past results as appearing more probable than they did initially

3) Clustering Illusion

see patterns where none actually exist

4) Recency Effect

give more weight to recent data

5) Anchoring Bias

a well-known problem with negotiations

6) Overconfidence Effect

people tend to grossly overestimate their abilities

7) Fundamental Attribution Error

Mistaking personality and character traits for differences caused by situations

40 Facts About Sleep You Didn't Know

clipper's remarks: Visit page to see all 40. Fact "- Scientists have not been able to explain a 1998 study showing a bright light shone on the backs of human knees can reset the brain's sleep-wake clock."

Clip Source: abc.net.au

40 FACTS ABOUT SLEEP YOU PROBABLY DIDN'T KNOW...
(OR WERE TOO TIRED TO THINK ABOUT)

-The record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.

- It's impossible to tell if someone is really awake without close medical supervision. People can take cat naps with their eyes open without even being aware of it.

- Anything less than five minutes to fall asleep at night means you're sleep deprived. The ideal is between 10 and 15 minutes, meaning you're still tired enough to sleep deeply, but not so exhausted you feel sleepy by day.

A new baby typically results in 400-750 hours lost sleep for parents in the first year

- One of the best predictors of insomnia later in life is the development of bad habits from having sleep disturbed by young children.

- The continuous brain recordings that led to the discovery of REM (rapid eye-movement) sleep were not done until 1953, partly because the scientists involved were concerned about wasting paper.

- REM sleep occurs in bursts totalling about 2 hours a night, usually beginning about 90 minutes after falling asleep.

- Dreams, once thought to occur only during REM sleep, also occur (but to a lesser extent) in non-REM sleep phases. It's possible there may not be a single moment of our sleep when we are actually dreamless.

- REM dreams are characterised by bizarre plots, but non-REM dreams are repetitive and thought-like, with little imagery - obsessively returning to a suspicion you left your mobile phone somewhere, for example.

- Certain types of eye movements during REM sleep correspond to specific movements in dreams, suggesting at least part of the dreaming process is analagous to watching a film

No-one knows for sure if other species dream but some do have sleep cycles similar to humans.

Elephants sleep standing up during non-REM sleep, but lie down for REM sleep.

clipper's remarks: Like the guy on the webpage this is linked to, I also found this letter among my dad's printed emails to me while I was away in university in another country. My dad has long departed since then, but every time I read these words Lincoln wrote to his son's teacher, they bring a tear to my eyes. Beautiful and sincere advice for anyone to follow.

Clip Source: vnicholas.wordpress.com

Lincoln’s letter to his son’s teacher

He will have to learn, I know,
that all men are not just,
all men are not true.
But teach him also that
for every scoundrel there is a hero;
that for every selfish Politician,
there is a dedicated leader…
Teach him for every enemy there is a friend,

Teach him, if you can,
the wonder of books…
But also give him quiet time
to ponder the eternal mystery of birds in the sky,
bees in the sun,
and the flowers on a green hillside.

In the school teach him
it is far honourable to fail
than to cheat…
Teach him to have faith
in his own ideas,
even if everyone tells him
they are wrong…
Teach him to be gentle
with gentle people,
and tough with the tough.

Teach him to sell his brawn
and brain to the highest bidders
but never to put a price-tag
on his heart and soul.

Teach him to close his ears
to a howling mob
and to stand and fight
if he thinks he’s right.

This is a big order,
but see what you can do…
He is such a fine little fellow,
my son!

15 Things you don't know about your Penis!

4. The average male orgasm lasts 6 seconds. Women get 23 seconds. Which means if women were really interested in equality, they'd make sure we have four orgasms for every one of theirs.

5. The oldest known species with a penis is a hard-shelled sea creature called Colymbosathon ecplecticos. That's Greek for "amazing swimmer with large penis." Which officially supplants Buck Naked as the best porn name, ever.

7. Only one man in 400 is flexible enough to give himself oral pleasure. It's estimated, however, that all 400 have given it their best shot at some point.

10. German researchers say the average intercourse lasts 2 minutes, 50 seconds, yet women perceive it as lasting 5 minutes, 30 seconds. Are we that good or that bad?

12. The penis that's been enjoyed by the most women could be that of King Fatefehi of Tonga, who supposedly deflowered 37,800 women between the years 1770 and 1784 — that's about seven virgins a day. Go ahead, say it: It's good to be king.

13. Better-looking men may have stronger sperm. Spanish researchers showed women photos of guys who had good, average, and lousy sperm — and told them to pick the handsomest men. The women chose the best sperm producers most often.

14. No brain is necessary for ejaculation. That order comes from the spinal cord. Finding a living vessel for said ejaculation, however, takes hours of careful thought and, often, considerable amounts of alcohol.

15. The most common cause of penile rupture: vigorous masturbation. Some risks are just worth taking.

Why Can’t You Tickle yourself?

clipped by: kittyxiii

Clip Source: www.neatorama.com

18. Why Can’t You Tickle yourself?

Much to the dismay of wacky masochist everywhere, the human brain is wired against self-tickling. Because the brain controls movement, it knows what your hand is going to do before you do it. Thus it anticipates the exact force, location, and speed of the tickle and uses that information to desensitize you to your own roving hands.

So why do we have a tickle response anyway? Turns out, it’s a defense reaction meant to alert our cave-dwelling ancestors to creepy crawlies that didn’t know their place, and the uncontrollable laughing fit that goes along with it is actually a panic response.

Even if you know someone else is about to go for your rib cage, it’s hard to turn the response off because a) your brain can’t anticipate exactly how and where they’ll tickle you and b) knowing someone is about to tickle you is usually enough to keep those panic receptors open and ready to go.
