The lecture suggests keeping our bodies strong and healthy is about understanding how outside things, like air, food, and activity, affect us. It explains the idea of "excitability," which is how our bodies react to things like temperature and what we eat, arguing that being healthy requires finding a balance in lifestyle and habits. Garnett gives easy-to-follow steps for living a healthy life, focusing on breathing fresh air, eating right, and exercising, all to help readers live better by taking care of their bodies.
