I'm slightly obsessed by people's disastrous attempts to improve the look of their perfectly normal teeth.
As you age your gums shrink no matter how good you are at oral hygiene. Capped teeth get dark gaps over them unless you get the caps maintained and replaced. Which is expensive and a fag.
Veneers are an invitation to a lifetime of expensive maintenance and pain ranging from occasional sensitivity to the full-on Marathon Man experience.
Then there's tooth filing which is still popular despite all the horror stories that came out about people undergoing it for that programme 10 Years Younger.
Actually, that's what made it popular for ordinary people, which is how cosmetic surgeons make the bulk of their money - celebs try it out first, usually as a freebie, and then thousands of other people want the look and trust a celeb endorsement not realising many celebs are stupid and grasping and get things done free in return for talking about it in a magazine.
Most beauty journalists do exactly the same thing, which is worse because their puff pieces infest health pages and fool readers that there's a 'science-bit' behind the article.
All these things can be done really well by a skilled practitioner who's more interested in his reputation than your cash. But people like that cost a lot of money.
I told you I was obsessed, didn't I? 
More importantly, I want to change my vote from Julie to Martin. Lots of people like Martin, especially women, and women make up most of the BB audience.
