And that’s what we call survivorship bias. Sure you’ll be ticking along fine until some Legionella or Botulism just kills you before anyone knows it, other than maybe the doctor if you see one on time and the coroner. Then the next you online just assumes no need to wash things with soap because you just blipped out silently from existence.

There’s a reason billions of humans didn’t populate the earth until modern sanitation and understanding of disease.

Now sure some dirt every now and then from gardening (you still breathe some in after all) will do you good, keep your immune system busy. You’re right on that. But eating carrots straight from the ground is just rolling an unnecessary gamble you don’t need. You’re not wrong in that too much sanitation isn’t good either - but you do misunderstand a bit what that means. You don’t have to wear gloves working the ground - unless you have open cuts. You don’t have to soap up your carrots - but you do gotta give em a good rinse. Just dial it back a bit and you’ll make it unlikely to end up in a miserable time later in life, while still getting those benefits. A castle is strong, but just takes one thing to sneak in to bring it down from the inside - best not invite too many invaders once it’s already been built
