I am 29 years old in Japan, but 28 years old in USA

 My birthday is May 1st. Actually, it is May 1st in Japan when I am writing this article. However, it is April 30 in Ohio now. I am 29 years old in Japan, whereas I am 28 years old in Ohio. I am a Japanese. Who could imagine that I meet the birthday of my 29 years old in USA, although I had never been away from Japan until December of 27 year old? Life is mysterious. Nobody can expect what will happen next. When I was (am) 28 years old, many exciting changes happened. I moved from Japan to USA, changed from unmarried to married, changed from non-PhD to PhD.
