Kim Cattrall is worried she might die of Alzheimer's disease.

The 60-year-old actress admits she is ''concerned'' about the condition after it took her father Dennis four years ago, but is trying to treat her dad's demise as a ''wake-up call'' to encourage her to enjoy her life even more.

She said: ''I'm concerned about Alzheimer's disease.

''It took my father. But that's your DNA . It's part of life. And I'm trying not to be so fear-based.

''It's a wake-up call to enjoy life, more than anything else. I want to make the most of the time that I have where I'm healthy and mobile.

''My mother is all there - she's 87 and amazing.''

The 'Sex and the City' star insists she's ''happy'' about the way her life has gone and is pleased she has kept her sense of humour throughout her 60 years.

She said: ''I think I'm just happy about choices that I've made. I'm accepting myself and gracefully going forward as much as I can.

''I like myself now. It's that feeling of surviving, that you've been through a lot of s**t and you've got through the other side and still have your sense of humour.

''That's what I think is intrinsically British about me - I can laugh about things.''

Kim admits she didn't anticipate going through life without having kids and even wanted children at one stage, but didn't want to become a ''science experiment'' by going through IVF.

She added to the Daily Mirror newspaper: ''It's been a really interesting point of getting older. I didn't anticipate not to have children, it wasn't part of the plan. It just sort of happened and evolved that way.

''When I was married to my second husband, Andre J. Lyson, I wanted to have children. I went to my doctor and he told me that it could happen but I would have to accept that I would become something of a science experiment. It was the very early days of IVF.''

Kim - who was born in Liverpool, north west England - has been married three times, firstly to Larry Davis from 1977 to 1979 before tying the knot to Andre in 1982 but they went their separate ways in 1989 after she had lived with him in Frankfurt and learned to speak fluent German.

She later married jazz bassist Mark Levinson in 1998 but they split in 2004.
