With your own children, you love them immediately - and with grandchildren, it's exactly the same.

I'm very good at being out of work.

Before my mother's diagnosis with Alzheimer's, I had heard of the disease, but hadn't known anyone who had suffered from it.

Walking is my main method of relaxation. I don't go over my lines or try to solve the world's problems, I just enjoy the scenery and the wildlife.

With all the lines I have to learn for TV scripts, I don't think I have any problems with forgetfulness - that's brain exercise enough for me.

The more telly you do, the more it feels like a factory.

With something like cancer, there is a feeling that you can fight it in some way or control your response to it, but with dementia there is the fear of losing control of your mind and your life.
