Have you ever eaten mochi? If yes and you're still alive, you're blessed. Do you know how many people have lost their lives by choking on mochi in Japan? It's 300 averagely every year. We probably should prohibit or at least impose a heavy tax on mochi like narcotics and alcohol, but there has been no such momentum in the National Diet of Japan so far.

Why do bees and hornets build hexagons? If we try to fill a plane surface with a single kind of polygons, there are three options: equilateral triangles, squares, and regular hexagons. Bees and hornets go with regular hexagons because regular hexagons are best in space-efficiency and second best in strength. This is the core point of the theory. What do you think?

Do you notice anything peculiar in the above image of the big forest at the bottom of Mt. Fuji? It's moss. You can see a lot of moss on the ground. It grows on the surface of tree roots crawling on the ground. The forest soil is made of lava. The lava soil is so hard and well-drained that trees can't collect and keep water from their roots without moss.
