I'm 82-year old Japanese male, really old. I worked in a New York-based advertising agency 30 years after working in a local ad agency about 10 years. So my business background was marketing and advertising, though it's irrelevant to my present life now. I'm a user of English Language & Usage site of Stock Exchange more than six years, where I serve as one of moderators since 2012. Japanese language is my native language and English is my second language. I studied Chinese language in a Beijing University 23 to 25 years ago. But I almost forgot how to speak it long ago.
