The other day, I watched a TV health program. Theme was blood pressure control in winter.
According to it, when we get off the bed in the morning, It had better for us to wear slippers. If in case of barefoot, blood pressure will rise rapidly for people with high blood pressure.
I think I have to be careful, even in the nighttime.
It is a quiet rainy morning, unusual. The reason is that there are few students heading for school. In my living town, there is a well-known high school for prep course, and in the morning and evening, the area around the station is crowded with students.
Perhaps, during this time, students are busy for the midterm exam.
In my case, it has been 60 years have passed since then.
