Hi everyone-!
Welcome back Karl:-) It's strange that more I get old, I feel that I want to study more than before. All the textbook kind of knowledge that I was forced to study when I was a child have become so much interesting and meaningful in my everyday life. The great thing about living in the U.S. is that people can go back to college to study at any age. I've seen 70+years old man studying in a college class with bunch of 20-some years old students before. There's a good, welcoming atmosphere for people of all ages in this country. How about in Japan ? Do retired people go back to college and study for fun??
