(I thought it'd peaked at $50.) And oil and food are linked, because both are traded in dollars. (And oil is a key input to food production.)

Today I saw a post which agrees with my position (i.e., that now is most like the mid-70's) but unfortunately I didn't capture it, so you'll have to take my word for it.
