We are both over 75 and just request the test every two years.
Same for my breast cancer screening - I just phone after 3 years.
The NHS stops so much routine screening over 70s which seems perverse to my way of thinking.
The staff who answer the phone are always really pleased that folks are being pro-active.
Unlike our GP receptionist _ I had to get decidedly firm with her before she would book us in for the routine blood tests - diabetes, cholesterol etc. It was over 6 years since we last had them.
Again, the nurse who actually did the tests said it was great that we were getting them done.
