In some remote communities that live without modern industrial lifestyles, people don’t get high blood pressure as they age — and it’s super rare, suggesting it might not be a normal part of aging everywhere.

People's blood pressure tends to go up as they get older—even if they don't eat processed food, sit around a lot, or follow a Western diet—so aging itself might be the reason, not just modern lifestyles.

Even in remote tribes that live totally naturally, blood pressure still goes up as people get older — which might mean aging itself, not just modern life, causes this change.

People from a traditional hunter-gatherer group in Cameroon don’t see their blood pressure go up as much with age compared to city-dwelling adults from another group, suggesting that living a traditional lifestyle might help keep blood pressure in check as people get older.
