Unfortunately, unexpected things can happen to us as we age...inspite of our enthusiasm for life.
In 1992 I lived and worked in Tokyo for a year. And one crowded evening on the train back home after work, I happen to sit next to this older, but English-savvy Japanese gentleman (it was a long train ride).
But among many other things, he happen to inquire if I was married? I said "no,...but divorced."
Then he stated that if I marry again (I'm age 42 at the time) "be sure to pick a much younger wife".
"Why" I asked?"
"Because when you get 'too old', she can take care of you".
I was too 'arrogant and cocky' then. Today at 75, he was a wise man.
As I think back on the cultural differences, in my later years...a younger Japanese wife would be much more suitable over a Thai wife. Why...? Japanese have much more integrity.
However, the Past is Past...and for me, it wasn't meant to be.
