At the end of the year, supermarket's cashiers are crowded with shoppers. I caught an old couple. Both of them seemed physically handicapped and had lots of luggage. In shopping for the New Year, the two seemed to have shopped more than usual luggage, but apparently it seemed to be beyond the limit clearly, whether for payment at the cash register or transportation.
From now on, it will be increasingly to see such a sight. Clearly, an aging society is coming soon.
