Apprentice star Karren Brady has revealed how a potentially fatal illness changed her life forever.

The businesswoman was treated for a brain aneurysm seven years ago.

She said: "I would never have done The Apprentice had I not gone through the experience.

"It made me realise that life is short – and fun – and that you should try new things. I really believe in life-long learning. The moment you think you know it all is when you don't know anything at all."

Her husband Paul said the illness changed his wife considerably.

He said: "It made her softer and she's less likely to get so fraught about the unimportant things that used to wind her up".

Brady, who started her working life at Saatchi & Saatchi aged 18 and is vice-chairwoman at West Ham United, said she now regrets going back to work within days of giving birth to her daughter Sophia 17 years ago.

She said: "In those days, there was no such thing as flexible working or a work-life balance."
