1. Thick Eyebrows: If an elderly person has thick and dark eyebrows without excessive white hairs, it indicates strong vital energy and life force.
2. Healthy Teeth: Contrary to popular belief, it is not normal for older individuals to experience loose or missing teeth. After the age of 80, an elderly person should still have at least 20 healthy teeth in their mouth.
Insufficient or unhealthy teeth can lead to gastrointestinal discomfort, decreased appetite, and weight loss, affecting overall health.
3. Bright and Lively Eyes: Eyes are the windows to the soul. If an elderly person's eyes are bright and lively, it indicates better coordination and reduces the risk of accidents such as falls when going out.
