Crickets that received the hot probe “overwhelmingly” directed their attention to the affected antenna – they groomed it more frequently, and tended to it over a longer period of time, he says. “They weren’t just agitated and flustered. They were directing their attention to the actual antennae that was hit with this hot probe.”

Nature invented diseases that would kill you by the time you’re 30 and yet I don’t see you running naked outside to go die. Nature has never been something to follow, and especially not morally.
