Why were people in the past healthier than today?

People in the past often had healthier lifestyles due to their reliance on natural, unprocessed foods and regular physical activity as part of daily life. They were less exposed to the high levels of pollution and sedentary habits that characterize modern living. Additionally, tighter community connections and less stress from technological demands may have contributed to better mental well-being. However, it's important to note that historical health was also affected by limited medical knowledge and higher exposure to Infectious Diseases.
