At the age of 60, often referred to as the critical period for determining longevity, it becomes more crucial to observe a healthy lifestyle, heed the body's warning signals, and undergo timely medical check-ups at the hospital. Starting at 60, many experience a range of illnesses that were absent in youth, all seemingly appearing simultaneously. These diseases have a significant impact on health, such as diabetes, hypertension, coronary heart disease, cerebrovascular disease, and even cancer, which are not only difficult to cure but also affect the lifespan. However, it is not advisable for people at the age of 60 to engage in strenuous exercise due to the body's limitations, instead gentle exercises like walking are recommended. Walking strengthens the physique and can also indicate whether the body is healthy, aiding in the early detection of diseases.
