Not having alcohol has kept the weight off around my waist; my skin feels so much better, and I am sleeping really well.
Smiling makes you and others feel better, and it makes you look younger.
Although I eat healthily, I do enjoy a greasy fry-up, but usually only once a year. I've also got a big Kit-Kat addiction and buy them in bulk.
I definitely think men prefer women more undone and natural than butch and masculine. They prefer a fresher, sexier, more feminine look.
I grew up in neighbouring Hawaii, where Tahiti is regarded as a brother.
I've slipped enough times over the years to know the peril of a too-smooth sole, so every time I buy a new pair, I take a pair of scissors or a piece of sandpaper to the bottoms to roughen them up. In my catwalk days, I even used to spit on the soles of shoes before I ventured down the runway.
When you get older, your skin tone changes; your hair probably changes colour, whether you dye it or not, and you just can't wear the colours you used to like anymore.
Whilst I may look good, I do find it hard to find the right man.
As the years go by, you get to know yourself better and learn what works for you.
My favourite scent... changes every day. I have a cupboard full - so many I can't begin to tell you.
Fresh seafood reminds me of Hawaii and eating raw ahi fish on the beach with a little soy sauce - instant sashimi.
A secret control slip is a wonderful invention. It sculpts and lifts the bum and smooths the hips.
If you believe, as I do believe, in reincarnation, they say that every time you come back, it's because you have to finish something. I've a funny feeling that my thing in this life is to have one relationship after another.
My fashion icons are Audrey Hepburn, Grace Kelly and Ava Gardner. Their classic looks and clean lines should be the cornerstones of your wardrobe - white cotton shirts, black Capri pants, pencil skirts and ballerina skirts.
My life has been charmed in the sense that I've met some extraordinary people. But at the end of the day, when you go home and you go to bed, and if you're on your own, you never think of yourself in that way. I'm sure not even people like Angelina Jolie think like that.
I think I'm living in the wrong century. I would have made a great courtesan. Not a mistress - I could never be kept - but a courtesan with my own rules.
I am thrilled to be modelling the debut collection of Always Aliza. Janet Reger was such an iconic brand throughout my modelling career, and it feels great to now be modelling her daughter's range for JD Williams almost forty years on.
I hate Botox, but a fabulous-looking friend of mine told me her secret was this gadget that uses electrical impulses to tone your facial muscles. It works!
There are loads of women that don't want children. What does it matter? I'm still a woman.
I'm not keen on the English way of eating outside, on the street. I want food that is clean, not impregnated with toxic fumes.
The average British woman is a size 12 to 14, but in modelling, a size 12 is considered huge, which is ridiculous.
There are lots of things I won't eat but would like to, such as croissants or ice cream - if I started, I'd scoff the whole tub.
I go to the gym four times a week for 45 minutes to an hour without fail; I like using weights for muscle tone and the bike and rower for my heart rate. I do quite a lot of floor exercises.
My sister Naomi and I always wanted to go to Tahiti. We planned a fantastic holiday to visit several islands, but at the last moment, Naomi cancelled. It was the first time I'd holidayed alone, and it was absolutely the best.
The two times I have cut my hair shorter, I've ended up out of work - so short hair is not an option.
I was brought up by parents who embraced the 1960s and taught me that being faithful isn't the be-all and end-all.
I think a mother needs to be with mothers. I don't know what they talk about.
I haven't eaten meat since I was 17, so I take Vitamin C, a B complex, Omegas-3-6-9, glucosamine, and antioxidants to make sure my body stays healthy.
But I'd made up my mind early on in life that I never wanted to be a mother.
A lot of women lose definition around their waist as they get older, which can mean their bottom half can look shapeless.
Monogamy is not something that's important to me. I don't think it defines love.
I'm not a pretty-boy kind of a girl; the Brad Pitts don't do anything for me.
As a girl, I lived in jeans, and my love-affair with them continues. Since I turned 50, jeans have become something of a uniform, whether it's a slouchy boyfriend fit for daytime or a leaner, fitted jean in a darker denim for evening.
I don't wear mini-skirts or shorts because I have thread veins on my legs and cellulite, and I won't wear tights.
When you're a model, you learn how to make the most of your assets - in my case, the smallish behind that is the legacy of my half-Japanese heritage.
I've been lucky: my Japanese genes - from my mother's side - and a lifelong moisturising routine have helped keep me looking good.
I lost count of how many times photographers and designers would tell me to lose a bit of weight, especially as I got a little older and my body started to develop.
I sometimes overeat or drink too much, but I don't eat chocolate, and I gave up smoking when I was 39.
For modern fashion designers, bones are beautiful. I don't know why, but so many people are obsessed with the skeletal look.
Most English people are horrified that I use soap, but I like it - it works for my skin. I try different soaps all the time, but I use very mild ones.
I'm good at many, many things, but the one thing I've never been good at is relationships.
We are constantly driven to believe that women should look a set age or be a certain body size, which is fuelling an obsession with ever more dramatic and invasive steps.
When I began modelling in my late teens, I started to earn a lot of money very, very quickly, but I'd never been shown how to manage it properly.
