This is a thoughtful article from the Japan Times. It’s worth a read. Check it out!
Let me give you a flavor:
There are rich elderly and poor elderly, but the bond that unites them — age — may be stronger than any class tensions, just as youth bound rich and poor youngsters together when the world was so incredibly young half a century or so ago. Japan, as everyone knows, is growing older and older. So is the world, but not at Japan’s pace. Of the world’s roughly 440,000 centenarians, 58,820, as of September, were Japanese.
Personally, I am not convinced that other countries will necessarily witness similar battles between old and young. There are cultural issues at work here as well. I think that in most Western countries, on public transport, an elderly person would still give priority to a pregnant mother.
