Methuselah's Children, The Martian Shop, and Unbreakable (or the trilogy of Unbreakable, Split, and Glass) are all basically the same story: someone unleashing human potential by showing that a certain accomplishment was possible. Same with the non-fiction TV series about the Mad Doctor's drive across America. All it takes is someone to show it can be done.
Unbreakable and Methuselah's Children have an even closer similarity, being based on the idea of finding the extreme tails of the bell curve of human traits.
