Do you think there is a connection??

I think you mean the Mayan calender.I'm not worried about it.The Spanish invasion was not predicted.Like most civilizations the priests predicted an end.It was to be white and come from the sea.The Spanish loosely fit.Their calender ends on that day.No prediction of the end came with it.The world has heated and cooled many times in it's history.Maybe we're causing it this time,but there's nothing mystical about it.Christians have been predicting the end of the world off and on since the death of Christ.I'm not worried they're right this time.Bottom line enjoy your life,however long it is.
