While lecturing during my second visit to Singapore, Dr. Eric Teo Choon Chew along with his wife Cynthia and their son, took me to the top of the Tiger Sky Tower. Billed as Asia's tallest free standing observation tower, it provided a fabulous view of Singapore, which is certainly one of the most beautiful cities I have ever seen. And so clean! There is no garbage on the streets anywhere (likely in part due to anti-littering legislation that is enforced, and to 'no gum chewing' regulations). As I mentioned earlier, exposing one's brain to new sights, sounds, smells, and tastes through travel can be age-proofing. And I’m definitely working on age-proofing mine!
