Q What is your secret to looking fabulous?
A I keep myself very busy with work at the clinic, eat based on how it will help me in terms of my health or fitness, sleep seven hours a day and exercise just a little more than enough.
I also floss five times a day as I am wearing Invisalign, which are virtually invisible and removable aligners, to correct my overbite.
Q How important is it for you to keep up with your fitness routine?
A I intend to continue improving on my fitness. I go everywhere by bus, MRT or walking.
Q Has there ever been a time when you were not fit and fab?
A From 1993 to 2011, I was unfit and out of shape.
I was a competitive runner in school. However, I cut down on my running when I started working.
I had to take care of my new practice, teach at the University of Toronto and take professional examinations from time to time. (I did my last professional exam when I was 38).
I didn't watch my diet then and weighed 80kg at my heaviest.
Q What motivated you to start running again?
A In 2011, I met the coach of my former high school in Hong Kong, who told me that as an old boy, I could run in the 5,000m event on sports day. So I trained and went for the run. That motivated me to start running regularly.
Q What is your diet like?
A I used to eat a lot of food. Now, I have a balanced diet.
