Everyday memory enhancement techniques

Boing Boing reports research showing that carrying out an additional motor task (such as patting the head) helps older people remember that they have carried out routines such as taking their daily medication. Enriching mental processing at the time of the task reduces duplication errors because people have forgotten completing the task initially. Comments on Boing Boing reveal the many similar techniques relatively young (presumably) people use to remember actions such as locking their front door.
