# Why Don't All Heavy Elements Decay into $^{62}\rm Ni$?

I read the question If we assume that protons don't decay, then will all matter ultimately decay into Iron-56 or into nickel-62?, but I have a different question concerning the decay that has nothing to do with quantum tunneling.

My question is this: If $$^{62}\rm Ni$$ has a higher binding energy than $$^{56}\rm Fe$$, why wouldn't all of the heaviest elements (even those man-made) decay into $$^{62}\rm Ni$$?
