Mars bar-my ... addict Keith Sorrell

BARMY Keith Sorrell is living proof that man can live on Mars – he’s eaten nothing but the choc bars for 17 years.

Keith, 37, munches a dozen a day for his breakfast, lunch and dinner.

He gets through more than 4,000 a year – even having Mars Bar drinks mixed with vodka or rum when he goes to the pub.

Single Keith said: “My love of Mars Bars started at school with one or two between meals.

“All my pocket money went on them and one day I realised I couldn’t get by without them.

"Now I can easily polish off 12 a day, more at weekends. I’m totally addicted.”
