Oh, I love that - greyscale as a warning.
For a while I had my whole phone on greyscale, but I don’t have trouble with spending time on my phone - it’s really the laptop that I have an issue with.
Maybe I should write software to conditionally greyscale my desktop/laptop screen!
Thanks for the link and details, so helpful!
A word that is sometimes used is “piquant”, rocket is just another kind of mustard essentially and it can be hot like mustard can be (think how wasabi is spicy; the greens are not as spicy as wasabi generally, but it’s on the same spectrum).
