Zachary Taylor – IQ 139.8

Contrary to popular belief, Zachary Taylor’s demise wasn’t due to overeating of cherries alone! The former military man probably had diarrhea or dysentery, which might have drastically worsened due to the little red fruit’s consumption.

Prior to these incidents, Taylor had proved himself to be an able commander during the Mexican-American War and justified his 139.8 IQ score with some brilliant decisions. As far as his presidency is concerned, the poor man had as little as fifteen months in office, and that couldn’t have been enough for Taylor to show his mettle!
