The article is wrong in many places. For example, it says: > –One study showed that that training is non-transferable. This means if one learns a sequence of numbers, the skill fails when one tries to recite them backwards or a new set of numbers. but just about every person who has ever memorized numbers with those memory techniques can recite the numbers backwards too. If you gain the skills to memorize one page of random numbers you can memorize a different one too, no problem.
