Word, you guys. Most memory supps are pure crap. They increase bloodflow to the head and to parts of the brain, but so does jogging, or spinning around until you fall down.
There was this intriguing memory system taught by "toastmasters" affiliates back in the day. Stop reading now if you find this trite or boring.
This old school veterinarian I know (who is hailed as the best and most successful vet in Charleston, SC) told me that it got him through vet school. (He graduatede top of his class) It basically involves memorizing specific images (a llama, a banana, a porche... etc) that can be linked to the number 1-100, based on the shape of the spelled out #, ignoring the vowels. (so, for example, by ignoring vowels in "one", you get "n". n is shaped kinda like an igloo, so the image for one can be "igloo". You spend several weeks memorizing these mental images that represent the numbers 1-100, and then at any point after that you have that list down pat, you can associate other lists (grocery lists, cranial nerves, enzymes, amino acids, whatever) to the numbered images, by linking them via imagination. So let's say the first item on a long grocery list is celery. You picture an innuit man carrying a bundle of celery into an igloo, or making an igloo of celery. The more outlandish the mental image, the quicker it'll stick. Then you keep on going down the list. Apparently, this technique, once mastered, is incredibly functional. It also has the benefit of instant-memory-placement within the list (You don't have to remember/recite items 1-43 to recall what 44 is, someone can just say "what is #44?" and you can think of the image associated with 44, then the item's relation to that image, and boo-yah, you recall it.
