The fascination of TV documentary makers for cosmetic surgery is as great as the public's increasing willingness to submit to the knife.

The message of Plastic Surgery Ruined My Life was clear: such surgery is bad for your health.

Ashley's breast implants made her a record-breaking double F. The operations were financed by glamour magazines in exchange for photographing her new assets. The price she paid was being ridiculed in the street as people stared and pointed. Now she's having them reduced to avoid further public humiliation.

Simon wanted a bigger penis. A series of botched operations left him with a "grotesquely distorted and twisted" member smaller than the original. An ex-Mr Mexico emerged from surgery to improve his pecs with double C cups. They were victims of "cowboy" plastic surgeons better described as butchers. They're widespread in the US and heading this way.

The NHS is no guarantee of quality. In the North-East, Stephanie, from Bedlington, in Northumberland, had liposuction because her right thigh was wider than her left through regular insulin injections. A post-op infection spread, leading to six years in and out of hospital as surgeons tried to repair the damage. The man who'd carried out the surgery fled the country.

Stephanie was left with no lower stomach, a disfigurement she felt unable to show on the camera. On a positive note, she's determined to return to her fun-loving life, but admits: "It's very hard when you're reminded 24 hours a day with pain."

I worried that Inside Bjork would take us on a fantastic journey around the Icelandic singer's interior. Happily, this proved a straightforward examination of the career of a performer Elton John called "the only true innovative artist in pop music".

Others - and I'm with them - were of a different opinon, saying they thought of her voice "as not quite human".

This is a charge that some might level against the House of Lords, the subject of Molly Dineen's fascinating documentary. For three years she patrolled the corridors of power as legislation was introduced to evict hereditary peers. A "secret deal" with Labour meant the reform was passed in exchange for 92 hereditary peers being allowed to stay after elections. The idea of standing for election clearly upset some of the older peers. Rather than subject them to that, you couldn't help thinking it would have been kinder simply to put them down like you would a sick animal.

As Labour refused to be filmed, Dineen concentrated on Tory peers. Efforts were made to show they're not the silly old buffers we think they are. This was only partially successful as some should clearly have been sitting by the fire, not sitting in the Lords making decisions affecting us. But we did meet a lord who manned the petrol pump at his garage, and another who watched Coronation Street. Without a seat in the Lords, he needn't worry about missing an episode now.

Another institution, Tower Bridge, was the first of Britain's Best Buildings. It turned out to be a bit of a fake as it looks old but only opened in 1894. The medieval-style cladding conceals a modern steel frame - a sort of reverse architectural plastic surgery in which something young was made to look old.
