Sheets? Yeah, they’re not getting changed weekly; towels, ditto. My sports kit gets washed occasionally in line with French government advice – as a French citizen, I consider that my patriotic duty. Bras: Rigby & Peller say you can get away with multiple wears if you have several in rotation (though I’m stretching that past what the late queen’s personal upholsterers would approve of). When it comes to my phone screen, well, I have the robust microbiome of a medieval peasant and rarely get sick, so what’s the problem?
