I remember seeing a current affairs segment from the 1980s where a reporter ran an experiment of asking old people to reckon market stall grocery prices in pre-decimal currency. Before #decimalization it was held in the popular press that the old people would never get used to this new money.
Almost none of the old people coped, and even made comments about how difficult it was.
Old people actually do acclimate to these things.
