Hi All
First of all Mayan prophecy was located at US side Guitemala
was Their Center . They know English and their own language.
Some of them are still alive , and simply denied any DOOMSDAY Prediction made by Mayans.However Indication's were about Earth like Earthquakes,Volcanos and Thunderstorms
Related to Earth not to sun.Unfortunately The stone found was related to sun , but other' were missing .According to Their Prophecy , they believed in 9 Gods , so 8 stones were
Perished or destroyed no one knows.The Spanish Invaders Eliminate this civilization , so there is a strong point that they might had no time make a new calendar.If you see the previous years , you will found the sun's direction was same everytime as it will on 31/12/2012.
So no DOOMSDAY will come in year 2012.The movie made by sony pictures put a great impact on people worldwide .

Sincerely
Gurbinder Sharma

Ritalin Vs Cocaine
Both Are Tranqulizers.Ritalin is a medicine drug while cocaine is a drug widely used by addicts.Ritalin is used by psychiatrists for patients of ADHD(Attention Defict Hyperactivity Disorder).Both have same physical and chemical structure.
Working: Both have same effect on brain as both are capable of increasing the Dopamine level a harmone essential for mind alertness.both stop the secretion of dopamine into brain.
However both are dangerous becoz high level of dopamine is also dangerous results into brain damage and the homicidal behavior of the patient.
