So 7 years with the current movement. You know, if i were the Poles, i'd move too, being harassed by the Russians, the Germans and every other nationality around them for centuries.

Joking aside.

I haven't found any numbers for how fast they are moving, but 7 years sounds off as the movement should accelerate as they are getting closer to each other, feeling the pull. Half this time i'd recon, perhaps even less.

Watch mother nature, she's up to something and i think we'll see a lot of unnatural weather, more than usual this year.
