You'll forget most of what you learn. What should you do about that?

It’s ludicrous, though, to suppose that checklists are going to do away with the need for courage, wits, and improvisation. The work of medicine is too intricate and individual for that: good clinicians will not be able to dispense with expert audacity. Yet we should also be ready to accept the virtues of regimentation.

Research suggests humans forget approximately 50 percent of what they learn within an hour, and an average of 70 percent within 24 hours.
