Health

Health is an obvious prerequisite of success in any form of learning. Here, only the greatest natural allies of SuperMemo are listed:

sleep - nothing can ruin a SuperMemo session as effectively as drowsiness; sufficient amount of sleep is needed to activate memory consolidation mechanisms

physical exercise - jogging and swimming have salubrious neurotrophic effects when accompanied by mental effort

oxygen - without fresh air, a SuperMemo learner will experience signs of extreme exhaustion as soon as in the first 5 minutes of learning

abstinence from smoking and drinking.
