As a brief distraction from my homework:
William Butler Yeats is generally considered to be the greatest 20th century poet of the English language. I find it humorous, then, that during one of the last letters he wrote, after receiving an operation (at age 69) to increase sexual potency, he told his friend that
I shall be a sinful man to the end, and think upon my deathbed of all the nights I wasted in my youth. ~W.B. Yeats
Yeah. How ’bout that.
