Read the primary article or dive into the live Hacker News thread when you're ready.
No, but the episode proved that where you place the tooth brush in the bathroom doesn't really matter (ie next to the toilet or far away).
It's literally going in your mouth. And rinsing it with tap water isn't going to fix that.
There's bacteria everywhere. I rinse mine in grocery-store-strength peroxide every few days to cut down on the 'problem'
Sadly gamma radiation generators will never be safe enough to be widespread for that.
Still could it be workable?
30 or more years ago (?), Consumer Reports did a report on toothbrushes and they did a follow-up note or article clarifying their recommendation of how often to change toothbrushes. Their recommendation was not because of bacteria as many readers apparently thought, but because the bristles get worn down and don't clean as effectively.
And the "toilet plume"? Is that more of a problem in Britain? Looking back at John Postgate's Microbes and Man (which I read back in the 1990s):
(That was written back in the 1990s or earlier; British folks and travelers can obviously provide more current insight than me, who has never traveled outside the U.S.!)This is just germaphobe pornography. Your toothbrush is fine. You’re less healthy if everything is like a clean room in your life.
