Thanks guys been in hospital today for 14 month ( read 12 month ) colonoscopy to check everything out ( not that there's much left to check , but nothing , zero, nil , ALL CLEAR no sign of rust or anything else.
Cheers bass
Just an update, cruising through old posts, given a use by date was maybe 24 months but targeted chemo at start of 2020 now 30 months is not out of question. such is life.
