My question is genuine though, I’m not biophysics expert, I know there are radioactive elements in our body, but are they worthless? Probably the least meaningful to sustaining life would be least reactive elements if that makes sence, but life is more about energy of chemical reactions between molecules, not individual elements

All the radioactive ones maybe?

Audacious. It’s in the post you made this comment to
