He was quite intense about sports. In the early days, when I was first (nervously) getting to know my father-in-law, we would go to the bowling alley, or play badminton, and you could tell right away that he drove himself to excel. He didn't just play sports.

Later—after I'd gotten rather ill in New York— I ended an aquired reluctance to be sporty that had lasted for years, and I decided to take up Tai Chi. 

I found a master on 23rd Street (Master William C. C. Chen, an original student of Grandmaster Cheng Man-Ching), and started practicing most days. It was William who kept me interested and going, picking up variations on form and teaching me the subtleties on our trips to Singapore. On a rare visit from my wife's family to New York, he came to the Tai Chi studio to meet the master that had been teaching me.

Even though he's a bit frailer these days, through age and Parkinson's, he still has incredible strength and agility. Despite the disease, his technique is ineradicable, and he just keeps going.

I get bested every time, and I'm still learning from him.
