The elderly

Japan has 126 million inhabitants. That number is deminishing. Probably there is too little immigration and Japanese women don't have enough children, less than the necessary 2,2 per woman that is needed to keep the number stable. As a consequence the number of elder people is relatively high. Not that this is a visible phenomenon in the streets, but we do see many old people. And what strikes us is that many of them are in bad physical condition. They are often very short, o-shaped legs, more or less crippled, walk difficultly with sticks or another aid and, most striking of all, many have hunchbacks, noses close to the ground. I remember seeing such handicapped elderly people at home, but that was when I was a child. It seems that in our regions we have overcome illnesses like these, or have we comfortably hidden them in our care-centers? 
And there are exceptions......
