When we say things like ‘people don’t change’, it drives scientists crazy, because change is literally the only constant in all of science. Energy, matter – it’s always changing, morphing, merging, growing, dying. It’s the way people try not to change that’s unnatural; the way we cling to the way things were instead of letting them be what they are. The way we cling to old memories instead of forming new ones. The way we insist on believing, despite any scientific indication, that anything in this lifetime is permanent. Change is constant.
