I wont disagree that light bulb is the greatest invention ever. Imagine life without light bulb. eveyone of us will be living in darkness at night or get the pathetic minimal light from a lighted candle.
besides light bulb, air-con is another great invention. Esp with the super hot weather nowadays, an air-conditioned room is like heaven to me. Plus I slp in air-con every night, i practically cant live w/o it.
The next greatest invention is GSP!!! oh my, cant imagine how i would drive ard without it. I can remem some routes for nuts. and map reading pose as a prob (even though i used to be a geo student). I can read a map but I will take a super long time to figure out. I have a poor sense of direction. never thought of the usefulness of GSP until I started to drive ard sg on my own since last wk.
