Thanks โอ๋-อโณ: I know of a few coutry medical doctors who hardly have time to eat and sleep properly. One in Nan works during the day at a hospital then evening till late at his surgery. Because, there are a lot of people who needs medical attentions and he sacrifices himself to serve them. [I think, he will burns out soon. But that's his life and he knows full well where he is going.]

Thank you for reminding me of my "trapping". I too am trapped in my own world with my very own boundary and conditions. I should look other ways and leave things for people to enjoy. But lately I have been looking at rubbish in our environment (on land, in water, in air, in books and media, in food and inside homes), I realize now I am also throwing a lot of (verbal) rubbish into (y)our environment. I should be more parsimonious with my output -- it should be true, minimal, relevant and useful.
