Is every day life really worth recording for future posterity? This was a question Andrew Jewson asked himself when he first came up with the idea of producing a life journal,' a record of the minutiae of an individual's existence which are often forgotten over time.

But if recent television programmes such as Who Do You Think You Are? show, there is an insatiable appetite for recording our experiences, no matter how insignificant they seem at the time.

Now Mr Jewson, a property developer by trade, but something of an inventor and entrepreneur too, has devised the Chrono, a specially devised record of events, people and places as they occur.

Mr Jewson, who lives in Little Chesterton, near Bicester, said: "My memory is appalling and it was something I first thought of about ten years ago. I was moving house a lot, had different jobs and lots of holidays.

"I am an avid photograph collector but I don't keep a diary, and I thought that if only there was something where I could just record the highlights very simply to give a snapshot of my life."

Then he came up with the idea of a page listing a grid of 100 years, for example 1960-2060, covering a whole lifetime.

A range of different subjects including family, love, money, friends and even pets would each contain one of these single page 100-year grids.

The finished Chrono is split into six categories - Activities, Brain, Consumption, Entertainment, Personal and Social, and each has six chapters. So the Entertainment section covers sport, music, television, films, books and culture.

Much of what you enter into the Chrono may sound trivial now, but in ten, 20 or even 50 years, it could well become fascinating either to you, or future generations.

Mr Jewson said: "The Chrono will tell you what the films and books are which will jog people's memories and the travel section will remind people of holidays and visits.

"And one memory will trigger another."

Mr Jewson has spent more than two years working on the Chrono project, investing a six-figure sum'."

The difficulty with it is that it is a new concept and not an easy sell, particularly at £175 each, although the finished article is beautifully bound in leather and is a quality product that should last a lifetime.

He said: "I am in talks with places such as Harrods, Selfridges and Liberty and I hope to be in a high-profile store for Christmas."

Mr Jewson is something of a serial entrepreneur with his previous inventions including a portable tennis scoreboard and a handheld ultra-violet monitor, designed to combat the risk of skin cancer.

He says he has learned from his mistakes. The UV monitor came about in 1990, perhaps a little too early, while the scoreboard proved just too expensive.

But his bread-and-butter lies elsewhere. Having completed his A-levels two years early at Radley College, he studied physics at Imperial College, London, before studying accountancy at Oxford Polytechnic.

After a year as an accountant, he grew bored and joined his father, Stanley Jewson, in commercial property investment and residential property development.

Mr Jewson senior had previously run the Oxford Garage Group, now Motorworld, and still owns garage properties. The development company is called SGJ.

Andrew Jewson clearly has a great deal of energy and ideas, which is remarkable considering he suffered from the debilitating condition, myalgic encephalomyelitis, or chronic fatigue syndrome, from 1989 until last year.

He was bedridden for six months and every aspect of his life was affected by the illness which leaves sufferers feeling exhausted much of the time.

Then, last November, after visiting virtually every specialist in the country, he came across a GP specialising in Reverse Therapy, a treatment designed to correct a dysfunctional hypothalamus gland, which some experts now believe is at the root of the condition.

After four sessions Mr Jewson was cured, without any medication or physical treatment.

He said: "I could suddenly see the light, psychologically and physically. It is like my brain has been re-programmed."

Now Mr Jewson is playing tennis once more and going jogging - activities he could not previously manage.

He also has more energy for his family -wife Natasha and daughters Scarlett, five, and three-year-old Kitty.

Another of his projects involves setting up a record label in Oxford which is designed to help his second cousins, Jake and Georgina Carter, a musician and singer respectively, as well as other aspiring individuals.

And no doubt Mr Jewson will be making notes on it all in his own copy of the Chrono. .
