Read the following text and answer the question.
I think I have had an exciting life. I'm 63 now, and I don't work anymore. I was in the army for 40 years. I retired when I was 60. I live in a small town in Louisville. I have lived here for 20 years. To be precise, I have lived here since 1995.
I have been to so many countries that I can't remember all of them. I've been to South Korea five or six times and Canada twice. So many things have occurred since I've traveled a lot. I have seen a lot of beautiful things and eaten some exotic foods like the ones I tried in the Philippines. I ate a duck embryo, namely Balut. It was the first time in my life that I have ever eaten a whole animal that has not been slaughtered yet. I still couldn't be assured how I could swallow that. So unbelievable.
