Day 30 - Skills Erosion

Is it possible to lose all the skills I've built up during my 10-plus-year career within 30 days? 

What good will I do my new employer (whenever that happens) if I can no longer finesse my way off a conference call that doesn't even need me? 

Or use my powers of good to force a decision maker to make a decision (in writing, of course. Otherwise it just doesn't matter)?

Mark Twain will get out of his grave and walk thousands of miles to my front door solely to pat my back. Oh wait. That's it. Night.]
