some patients and elderly due to their bad health may have this problem, as well as children who were not taught to stay clean, to keep sweat and body odors in check and to generally be groomed - hair, nails, dry skin, an open wound crust, teeth, eyes and ears - evrything open and visible and also the whole body for the sake of personal health and also aesthetics for others to be able to be around.
we all know how essential this is. but sometimes, when you say for them to stay clean, people might get offended.
any thoughts on how to effectively, without sounding blunt, tell people to watch their hygiene.
