I loved reading all these messages as, you see, I have had this kind of very poor memory all my life! I forget names, faces, numbers, places dates etc etc. There's still a big panic in my tum when I realize I've lost something very important. But mostly I've coped for 73 years and of course nowadays a lot of docs etc can be reprinted. Things can be replaced and of course I can read a book twice and see a film a second time without remembering all of the plot or ending.
The DVLA were particularly nice and helpful when I thought I'd binned docs.
As regards statins, my brother is losing his (was much better than mine) memory on them and there is plenty of anecdotal evidence that this is a side effect. Porridge will also lower cholesterol - works for me, though my memory hasn't improved!!
