Years ago I was working in Japan and spend some time in Tokio working long days and drinking too much at night. One morning my mate said to me at Breakfast dod you feel the earth tremer last night, I looked at him blank and said no, slept right throuh it. Do the same with most thunderstorms as well. Mind you the time I Was in Japan before that I was sat in the baths they have and the whole place shook and mde me jump out, when I looked outside people were just walking around as normal. What scared the life out of me was normal to them
