This morning I laughed a lot with my wife when we happened to watch one NHK broadcast's short program that introduces simple daily excercise.Though our public broadcast NHK has featured such program from long time ago,what was unusual of this time is that it comically tells how we corporate employees can find time in our busy life to refresh our body by casual excercise.For example,the excercise shown this morning used arm holders while we're in the train by hanging on it and twist our body.I've never laughed so much while watching NHK that usually has serious documentary programs or news.
