If everybody asked themselves this question from time to time, we might treasure our time on earth a bit more. We might watch after our health better, care more about the person next to us, show more concern for the earth, and do what we can for those in need. We wouldn't be living in vain. We might just let ourselves forget about unhappy little incidents.
而假如每個人都常常這樣想，或許，我們會多愛惜一些時間，多珍惜一些健康，多疼惜身邊的人，多愛護腳下的大地，趁著還有今天，多為需要的人盡一份力量，讓我們的人生不至於留白。
