Now I knew what it takes for Nigella Lawson to go to bed, as she puts it, "a lot happier" - a bulging fridge and a full pantry. She can put her head on the pillow and sleep soundly in the knowledge that she has everything she needs in the kitchen to make the next day's meals.

Like a boy Scout - although, to be honest, Nigella, with her voluptuous figure and saucy demeanour, looks nothing like a boy Scout - she's always prepared.

Nigella is back and this time she's playing at being a fast lady, serving up suggestions for fast food, namely food that doesn't take a lot of time to prepare. As she tells us from the outset, just the thought of dinner in the middle of the working day used to make her "tense and tetchy", adding, "At the end of the day, it really can push you over the edge".

Nigella's fast food isn't what you may understand as fast food. Not a hamburger in sight. Just roast poussin with sweet potatoes and salad, fresh stuffed pasta, and quick calamari. And to finish off, when you return home after a night out, how about caramel croissant pudding?

The latter is "luscious, smooth, flowing". A bit like Nigella, who gets a bit sniffy in a Radio Times interview over the term "gastro porn" being applied to her cookery programmes. But any show that ends with her sitting in bed wrapping her lips round a creamy pudding, while sighing "it's everything I hoped it would be and more", probably deserves that description.

Grandad's Back In Business is another job interview programme, a small-scale version of The Apprentice with an added factor - age.

Raymond has been a hairdresser all his life and now, at 60, is having difficulty finding a full-time job. He's competing against 17-year-old Rebecca for a trainee's job in a top London hairdressing salon.

There's never really any doubt who's going to get the job. Who would you choose: an older man set in his ways or a young girl ready to be moulded into the way you want her to work?

The age thing is what makes the show worthwhile, highlighting some of the problems and prejudices the more mature person - as someone approaching 60 I refuse to call Raymond elderly - faces in the workplace.

Raymond's dilemma pales in comparison with what happened to Danny Biddle, who has the dubious distinction of being the most seriously injured survivor of the terrorist attack on the London Underground two years ago.

He lost both legs, an eye, had several heart attacks and faces being medicated for the rest of his life. Yet his courageous, moving story tells how he's refused to let it ruin his life. He's married his fiancee, returned to work and got on with his life.

He also takes the opportunity to take a few well-earned swipes at a government compensation system which, among other barmy things, doesn't allow him to claim for more than three injuries.

The combination of the testimony of the two men, both former soldiers, who helped save his life as he lay terribly injured in the tunnel and reconstructions of the incident help convey the sheer terror and horror of what the attack and its repercussions.

It also makes you believe in fate. Danny shouldn't have been on the train that day. He'd been unwell and was running late for work, then his journey was delayed by a series of incidents including broken ticket machines and a burst water main. They all colluded to place him standing next to the bomber on the train as he detonated his bomb.
