Have trouble remembering your neighbor's name? Don't know where you left your smartphone last night? New Yorkers by necessity have lots to remember -- unfortunately, too much.

But don't despair! Memory can be improved, say the "athletes" competing in Saturday's 17th annual USA Memory Championship. The event, which challenges players in a series of mental challenges including memorizing decks of cards, numbers and names and faces, is being held at Con Edison's Grand Auditorium in Manhattan.

This year's competitors include a dentist, nurse -- even an eighth grader from New Jersey. Spectators are welcome; there's no admissions fee.

amNewYork spoke to three current and past competitors to learn their tips and tricks for memorization.
