Experiment: Repetition is a form of change

Every morning before getting out of bed, touch your nose with your thumb. Do this for 14 days.
If you miss a morning, start the fourteen-day period over.
When you have completed a fourteen-day cycle eat a cookie and start another fourteen-day cycle.
Once again you will touch your nose with your thumb each morning before you rise.
If you miss a morning start the cycle over.
When you have completed the cycle eat another cookie. You may choose to continue for another fourteen days or stop there.
You can repeat the cycle, as many times as you like, but do not stop in the middle of a cycle.
Keep a record of the days you have followed through with the experiment as well as any breaks in the cycle and your observations.
