When we went to our Reno, NV home - a more typical American society than San Francisco, we did notice that almost everyone was overweighed there.......many children included. Then when we went to the restaurant, we noticed how gigantic the hamburgers were. Double or triple meat patties, cheese on each deck, beacon, mushroom, tomato, lettuce, onion, pickles, the whole works with Mayo dripping down on the side. The burger must be piling up to at least 8 or 9 inches high. Nobody should consume that much food in one meal. Now even the fast food restaurants, e.g. McDonald's, Burger King, Jack in the Box, food are getting bigger and bigger also due to competition.
May be I should consider moving back to HK, so that I can lose some weight. While in HK for the 3 weeks, I had never done so much walking in my life. I didn't realize I was in such bad physical shape until we needed to go across the streets, we must climb up those damn stairs at the overpasses and some MTR stations.....worse in GZ and Shenzhen. I felt like I'd die of a heart attack each time I reached the top of the stairs. In the USA, we sure are living in a NOT very healthy society where our cars take us anywhere........no walking whatsoever. We must change our lifestyle somehow.
I forgot who said it, but it goes: Americans like things big, loud and fast.
