It is certainly true that many people maintain their youthful vigor and flexibility well into old age. And as the years pile up, so does experience. Our thinking matures and we are able to act in a more rational manner to take care of our bodies. We no longer eat and drink to excess, nor do we live the disorderly lives we lived when we were younger.
的確，許多人直到壽終，都還能保持年輕時的活躍、彈性並充滿活力；而由於年歲的累積，許多人經驗更豐富，心智更成熟，較能理性節制，不再像年輕時暴飲暴食，起居無度，反能妥善保養身體的健康，以自己的人生經驗與智慧，繼續對家人、社會有所幫助。
