It seems that sunspots have about a ten-year cycle. When they are active they multiply and enlarge; when they weaken they decrease. It is said that their dynamics strongly affect human psychology, but nowadays many people have become arrogant, and don't realize they are so small compared with the scale of the universe. It can't be helped, but maybe if you have a drink and listen to Bamboo-Na's album, you might have some kind of awakening!
