How the huamn mnid raeds (so what’s the point of spelling properly?)

Aoccdrnig to a rscheearch sudty, it  deosn’t mattaer in waht oredr the ltters in a wrod aer; the only iprmoatnt fatcor is taht the frist and lsat ltteres be at the rghit plcae. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
