Why do baseball players, for example, who are multi millionaires in this day and age take jobs as coaches well after retirement from playing. The answer is clearly that they want to give back and/or they love the game so much they don't want to ever leave it. What a nice thought that you still want to do what you have been doing long after you finish getting paid for it. That is not to say that you will not be paid for teaching in Asia because you will and you will be able to live well.
...and having a golf course nearby in in the middle of winter is not a bad perk, wouldn't you say?
