Demographic changes and the pandemic are propelling consumer-goods companies to take a fresh look at a group of shoppers who are often ignored: the elderly.  As
 
people live longer
 and have fewer babies, the number of over-65s surpassed those under five globally for the first time in 2018, according to United Nations data, and the trend has accelerated since.  The pandemic has 
disproportionately harmed older people, which executives say has highlighted the importance of staying healthy later in life.
