The link between sleep deprivation and psychosis was further documented in 2007 through a study at Harvard Medical School and the University of California at Berkeley. The study revealed, using MRI scans, that sleep deprivation causes the brain to become incapable of putting an emotional event into the proper perspective and incapable of making a controlled, suitable response to the event.

Yeats describes the inspiration for the poem coming from a ``sudden'' memory of his childhood while walking down Fleet Street in London in 1888. He writes, ``I had still the ambition, formed in Sligo in my teens, of living in imitation of Thoreau on Innisfree, a little island in Lough Gill, and when walking through Fleet Street very homesick I heard a little tinkle of water and saw a fountain in a shop-window which balanced a little ball upon its jet, and began to remember lake water. From the sudden remembrance came my poem ``Innisfree,'' my first lyric with anything in its rhythm of my own music. I had begun to loosen rhythm as an escape from rhetoric and from that emotion of the crowd that rhetoric brings, but I only understood vaguely and occasionally that I must for my special purpose use nothing but the common syntax. A couple of years later I could not have written that first line with its conventional archaism -- ``Arise and go''--nor the inversion of the last stanza.'' The poem is featured in passports of Irish citizens.^≥

Since 1973, most collegiate, amateur, and professional leagues have adopted the rule or some variant. MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.
