My ears ‘ring’ all the time. It’s like having cicadas inside, 24/7. I suspect this is an undesirable thing – and probably a byproduct of shotguns in my youth. But cicadas are summer creatures, and so this can only mean one thing: it’s always summer inside, and although I’ve never blown up a tube and gone down the river, I think I want to.
Update: A few days later – An accidental discovery since the above posting suggests ibuprofen use may also contribute to the chirpiness of the cicadas. Modern living.
