THE mental acuity which men experience after ejaculation lasts for precisely 120 seconds, scientists have confirmed.

The state, in which men see and comprehend the world as it truly is and are capable of great insights and discoveries, fades exactly on the two-minute mark as they plunge back into guilt, shame and vaguely fancying a wank.

Professor Henry Brubaker, of the Institute for Studies, said: “It lasts about the quarter of the length of an average act of intercourse. One of nature’s delightful patterns, like the Fibonacci sequence.

“During that time men realise they shouldn’t be having an affair with their wife’s best friend, or that pornography has an adverse effect on both performer and consumer, or solve superstring theory with 11-dimensional membrances. Then they forget.

“After that two minutes is over, they descend back to ordinary consciousness and begin closing PornHub tabs, fumbling to grasp revelations which were so clear a moment earlier.

“If it could be prolonged then a cure for cancer or the harnessing of cold fusion energy would be within our grasp. But sadly, like everything else worth doing, it’ll have to be left to women.”

17-year-old Ryan Whittaker said: “I achieve post-nut clarity upwards of four times a day. It’s exhausting.”
