I’m someone who builds up earwax easily, leading to infections.
For the last decade, I’ve been regularly scraping it out with metal spoons. I’m even used to accidentally tapping my ear drum.
Last time I was at my doctors he commented (to the intern in training) that my ear canals are well sloped and naturally clean themselves, and I corrected him. Glad to know he didn’t observe damage I’ve been causing.
Now that is a good shower thought!
