@edgarblythe,
I think the thing about elderly smelling is way overblown. I shop and live in south FL in an area where elderly are concentrated. I donāt smell any difference from the younger public. Of course, Iām 73 yrs of age so I might not be a good barometer. Most people would say Iāve a good sense of smell and food tastes great to me.
I do know some elderly that put their winter clothes in mothballs. So, perhaps thatās āold people smellā.
