I think a lot of people don't realise how much of what makes "them" them is gut biome and your brain retrospectively assigning yourself agency for actions your body decided on (flinching from hot surfaces is one).

We just keep finding more ways that gut bacteria influence our diet and behaviour. And if you obey your gut flora and eat sugar instead of protein, you'll allow them to increase which expands their influence over you. Or that part of you, since where's the line?
