Were the Mayans right?

[Nemesis]

I think the earth is ticking as normal I am sure every ten years we go through a new phase, cold/hot.

Civil unrest times are a changing and anyone in power knows you can only have your slaves feeling happy and safe for so long before they want to rebel, shake em up some and make them look to master as protector for another decade.

As for disaster, has anyone here looked back over say 50 years to find out if we are going through more now than before?
