todae's iron presentation was cancelled. shld i be happy or sad? maybe more to the happy side bah. cos i think for me we are like going a little off- track, lost our sense of direction. but then also cannot completely blame us for going off track. i jus feel tat the qn post was too wide n general. biological importance of that metal. to me i interpreted it as how tat metal is important to the human body. but i think after some explanation by dr. chia, i think he wanted more on the chemistry. i think i roughly got wat he wanted. but then info quite difficult to find leh. moreover so many grps doing on iron... n they like pro e lor... able to explain the chemistry behind it. do u think im doom? haha.
