Sally Feldman’s article (Dismiss ‘grannies’ as frail old biddies at your peril: they’re some of the toughest activists out there, 20 August) reminded me of an incident a few years ago. I went to present a neighbour with a bottle of prosecco for their birthday. “Who is it?” someone inside shouted. “Just an old granny,” came the reply. I’m happy to be a granny, even an old granny, but not just an old granny. My young granddaughter was appalled and said: “Let’s go.” We did.

• Devi Sridhar tells us that any alcohol is bad for us (Opinion, 20 August). How times change! As an anaemic teenager in the 1960s, I was “prescribed” a small glass of Guinness to have with my evening meal. There was also a suggestion in the late 60s that it was good for new mums.
