I'm mad about gardening. I have an allotment on the other side of Hampstead Heath, and I keep three hens in my garden.

I work every day from 9:30 or so until lunchtime. In the afternoons, I become a normal person - go shopping and do the garden and look after my grandchildren.

I do believe that we baby-boomers are reinventing ageing as we enter it. We're living longer and expecting more from life; the success of 'The Best Exotic Marigold Hotel,' and other films and novels about finding love late in life, have shown that if we're up for it, there are adventures awaiting us.

My parents were both writers - they would type their manuscripts sitting side by side on the veranda of our house near Watford - so I wanted to do something different. I wanted to be a bluegrass singer, an architect, a landscape gardener, or to do something with animals.

It's not a failure if a marriage or partnership ends after a certain number of years. I think, in general, we expect too much of partners. We can't fulfil a person's every single need and, after ten years or so, many relationships wear out. If we were more philosophical about it, we wouldn't try to blame the other person or be bitter.

A garden is made of hope.
