Hundreds? 200 years ago most people did not even have birth certificates. I can think of multiple famous examples of people who lived in Europe 500 to 800 years ago where we don't know their real age. In existing countries with poor state capacity, a lot of people don't have legitimate birth certificates and there is some evidence that they make up their age to some degree. For example on surveys in such countries there are too many people reporting round number ages. My experience in such countries is that you can find very young looking males riding motorcycles late at night around the city and anybody can buy alcohol. That's how it was in the United States "hundreds" of years ago. Please read a book.
