I'm so tired, I haven't slept a wink
Excuse me while I whimper in the corner:
"Greater numbers of female partners leads to fatigue in males. They start producing smaller sperm packages," [biologist Sylvain] Charlat said. "Unfortunately, the females ... instinctively know that the packages are smaller and that their chances of having been sufficiently impregnated after mating are lower than usual. This just makes them more rampant."
Dr Charlat was actually talking about butterflies, but this still spooks me.
