Well, I think you're right and this is because of tredition. But I also think that it is because their lifetime. In 17-18 century people hadn't lot of medicines, and they sometimes died just because virus. People's usual lifetime was 46 years. But after 20th century, there was big progress in medicine. So, statistically people life during 81 years. So, our 18 is their 10.
