An unexpected benefit of my career in biochemistry has been travel.

Golf is growing, and there are more good young players, but you don't see them going abroad. It's so expensive to travel.

You have all these people in the city and everything has become centralized. If you live outside the city and you need a birth certificate or some official paper from the government, you have to travel to the city.

My goal when I started out was to get to the point where I could tour a lot and make a living, which means getting paid enough to hire my own band, travel and end up with a bit of money, but I'm still nowhere near that point. Because I didn't have a band and fan base when I started, I did everything backward.

I think travel is probably the downside of playing professional golf, but you've got to do it.
