Mihaly Csikszentmihalyi (mee-HIGH CHEEK-sent-me-HIGH-ee), author of Flow, a book about the psychological benefits of highly engaging activity, died at the age of 87.

From his NY Times obit:

Flow, he argued, was a state of mind, a level of concentration in which outside stimuli, even time itself, seem to fall away.
