Here are a few of my techniques....:hump:
1. Do the alphabet backwards in your head
2. Think of work (I was thinkin of what to include on a data requirements checklist for a new consulting project last night while laying the lumber)
3. Count spots on the headboard, ceiling, lower back as the case may be
4. Switch positions and take a break when things get close
5. Fire off a test rocket an hour to two before
6. Try to remember the names of everyone from a prior job, class, etc
7. Do the multiplication tables in your head (this used to be my number 1, some Senior in my Freshman Spanish class gave me this gem back in the day)
