A couple of weeks ago, I was in Hong Kong and I caught this ad on national TV. TV commercials in their most entertaining way, reflect the prevailing zeitgeist of a country. As a physician, I am especially attracted to health messages conveyed in TV ads and this particular 30-second short is evocative.
It shows a reverse-motion playback of a middle-age Chinese gentleman ingesting various junk food. The video pans out in the latter part revealing all sorts of food substances the digestive system puts up with in the first 50 years of a human life. Very strong and powerful graphical message there!

The ad is commissioned by Hong Kong Cancer Fund and posters like the one above are ubiquitous around subway stations in Hong Kong. I think they did a commendable job at that, advocating public awareness on bowel cancer. Liow Tiong Lai, take note!
