One thing that comes to mind is https://en.wikipedia.org/wiki/Kinetic_isotope_effect https://en.wikipedia.org/wiki/Kinetic_isotope_effect , although this seems to mostly affect elements that only have a few protons, like hydrogen or oxygen. Still, it adds up enough so that replacing most of the water in your body with heavy water (D₂O) would be fatal.. But, you'd have to drink exclusively heavy water for a long time to actually reach a toxic dose.

- zeristor 6y agoYes thanks for reminding me about Heavy Water ice, and how it sinks in a glass of water too. Also I have subscript envy, and shall scour the Internet as to how to do subscripts in HN.
- FreeFull 6y agoI used the subscript 2 unicode character (U+2082). As far as I know, HN's formatting doesn't include anything to do subscripts. (At least, https://news.ycombinator.com/formatdoc https://news.ycombinator.com/formatdoc does not mention it.)
