Will The World Really End in 2012?


We all know that the world is going to end in December 2012 because a giant solar eruption is going to swallow the Earth. Or is it supposed to be the implosion of the Yellowstone Caldera? Reversal of the global poles? Does anybody even care about how the Earth will end if we are all doomed anyway?
Apparently, yes. NASA has set up a Frequently Asked Questions page on its website to answer questions pertaining to the end of existence. According to NASA, there is no scientific evidence that the world is going to end in 2012. Contrary to popular beliefs, put your trust in science and do not set up the foundations for that underground bunker just yet.

Don’t panic! Mayan timekeeper says world WON’T end in 2012… as it’s only a calendar change

  • Leonzo Barreno trained as timekeeper by Mayan elders
  • Many believe its calendar marks end of world on Dec 21
  • But professor says it just marks start of new calendar
Many consider it a joke although others are scared we might never live to see next year thanks to the Mayan calendar’s ‘apocalyptic’ prediction.
But Mayan expert Leonzo Barreno, of Saskatchewan, Canada, says the ‘apocalypse’ concept is a false interpretation of the Long Count calendar.
The University of Regina journalism professor said Mayan elders taught him that December 21 this year simply marks the start of a new calendar.

David Blaine: How I held my breath for 17 min

David Blaine is world’s most famous magician. As a magician, David Blaine has gone to great lengths to challenge himself with tasks that doctor’s say are “not possible. He’s been buried alive in a coffin in New York City for a week, frozen himself in a block of ice for 3 days and 3 nights, stood on a 100 ft pillar for 6 hours, to living in a glass box in London for 44 days.


He’s done a lot of drastic events that I wouldn’t think twice about doing. But as a magician, he was not satisfied by succeeding with just those tasks. “I wanted to see how long I could go without breathing, how long I could survive with nothing… not even air.” Little did he know that it would become the most amazing journey of his life.



In this video he tells us about how he conquered his most difficult challenge of holding his breath for more than 17 minutes while breaking a world record. He teaches us that nothing is impossible if you are passionate enough to achieve it and if you are ready to fail and start back over and over again.


IMPOSSIBLE IS NOTHING!

Heart Attacks & Drinking Warm Water


This is one of the best article on this topic. Not just regarding the hot water following your food, but on the subject of Heart Attacks. The Chinese & Japanese drink hot tea or coffee with their meals, not chilled water or cold drink, perhaps this is the time we adopt their drinking tradition at the same time as having meal.

Why Hot Water is Best During Meal
For all those who love to drink icy water, this post is applicable to them . This is good to get a mug of cold drink following a lunch or dinner. But, the cold water will solidify the oily things which you have just consumed. It will decelerate the digestion. Once this ‘sludge’ reacts with the acid, it will break down and be absorbed by the intestine quicker than the solid food. It will line the intestine. Very soon, this will turn into fats and lead to cancer.
It is best to drink hot soup or hot water or even hot tea/coffee after a meal.

Common Symptoms Of Heart Attack…
A serious note about heart attacks – You should know that not every heart attack symptom is going to be the left arm hurting
Be aware of intense pain in the jaw line.
You may never have the first chest pain during the course of a heart attack.
Nausea and intense sweating are also common symptoms.
60% of people who have a heart attack while they are asleep do not wake up.
Pain in the jaw can wake you from a sound sleep. Let’s be careful and be aware.
The more we know, the better chance we could survive.
A cardiologist says if everyone who reads this message sends it to 10 people, you can be sure that we’ll save at least one life. Read this & Send to a friend. It could save a life……..So, please be a true friend and inform  to all your friends you care about. 



I JUST DID.




Valuable Information!
Correct timing to drink water, will maximize its effectiveness on the Human body.
Two (02) glasses of water – After waking up – Helps activate internal organs
One (01) glass of water – 30 minutes before meal – Help digestion
One (01) glass of water – Before taking a bath – Helps lower blood pressure
One (01) glass of water – Before sleep – To avoid stroke or heart attack

Please share to all your relatives and friends
End is not the end. In fact E.N.D. is "Effort Never Dies"
& if you get NO in answer remember N.O. is "Next or New Opportunity ". So always be positive in life !!!

Amazing Technical fact behind avatar movie

The entire rendering of the movie AVATAR takes 1 petabyte of storage space! This is the equal to
500 hard drives of 2TB (1 TB equals 1024 GB) each and also equal to a 32 year long MP3 file! PS- With millions of money spent on storage device I am not
amused why the movie budget hyped to 300 million.



Also look at some funny facts about the film.


1. lots of dough
  James Cameron originally planned to have the film completed for release in 1999. At the time, the special effects he wanted increased the budget to $400 million. No studio would fund the film, and it was shelved for almost 10 years.


2.Title error
   An early casting call for the female lead was posted, identifying the movie as James Cameron’s “Battle Angel.”


Michael Biehn
3. Casting dielemma
   James Cameron’s go-to action guy, Michael Biehn, who starred in Cameron’s “The Terminator,” “Aliens” and “The Abyss” — was considered for the role of the tough-nut Col. Miles Quaritch. Cameron ultimately had to pass because he’d already cast Sigourney Weaver (who starred opposite Biehn in “Aliens”) and he didn’t want people to think it was “Aliens” all over again. The role eventually went to Stephen Lang.


4. CGI rules
   The movie is 40 percent live action and 60 percent photo-realistic CGI. Most of the motion capture technology was used for the CGIscenes.

5. Sam's audition
   According to Sam Worthington, he was invited to the casting via a phone call. He didn’t know anything about the script, nor was he told the director’s name. Sam was initially disappointed, thinking it was “another waste of time.”


6. Show me the money
   “Avatar” is the highest-grossing film of all time, bringing in $700 million domestically. James Cameron’s previous film “Titanic” was the first film to gross $500 and $600 million domestically.

Thanks a lot..




Google's Driverless car - Incredible machine

       The Google Driverless Car is a project by Google that involves developing technology for driverless cars. The project is currently being led by Google engineer Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory and co-inventor of Google Street View

Google Gets The License for Driverless Car
The U.S. state of Nevada passed a law in June 2011 concerning the operation of driverless cars in Nevada. Google had been lobbying for driverless car laws.The Nevada law went into effect on March 1, 2012, and the Nevada Department of Motor Vehicles issued the first license for a self-driven car in May 2012. The license was issued to a Toyota Prius modified with Google’s experimental driver-less technology. Source
“I felt using the infinity symbol was the best way to represent the ‘car of the future’.” Department Director Bruce Breslow said. “The unique red plate will be easily recognized by the public and law enforcement and will be used only for licensed autonomous test vehicles.”
