It's good practice to only use `before` blocks to set up data that's used by *all* of the tests within the same `describe` block. Most of your tests below don't use all of the test people, but they're all re-initialized for every test anyway. This also puts the setup data for the tests far away from the tests themselves, making them harder to read (say you're down on line 58 and find yourself thinking "wait, what was Person 3's weight again...?"). In this case, a smidge of duplication in exchange for more clarity would be preferable.
