I had a bone density test about 10 years ago and was diagnosed with osteoporosis in my spine and hip. I'm not aware of any particular problems I have with osteoporosis, however. I just know I've got it. I take a pill every week called alendronic acid which is supposed to help stop the spread of the condition.

I had a knee replacement in May last year, but that's because I have arthritis. The surgery made a huge difference to me. I can walk now which is something I couldn't do properly before. I can climb stairs, too, although going downstairs is still difficult.

When I had the knee replacement, they got me up the same day. I was walking with extreme pain for three days, after which it gradually subsided. Then I went to a wonderful convalescence care centre for six weeks.

My knee had been troubling me for four or five years, but I was frightened of having an operation. In retrospect that was silly. Well, not silly — because my doctor told me that 80 per cent of people are fine afterwards, but 20 per cent still experience issues. Yet early presentation is very important in everything. I wish I'd gone sooner.
