While such vigilant tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly.

Older Japanese regard post offices, which play a social function (postmen check up on old people, for example, and pick up their prescriptions), as a mark of civilisation.

The NACC report found there is a lack of awareness about the right nutrition for older people, with many older at risk as those hired by direct care do not need official checks.
