Allen Carr, whose books have helped people all over the world to quit smoking, has been diagnosed with lung cancer.
Mr Carr, who is aged 73, quit smoking in 1983. At the time, he had a 100-a-day habit. Since then, he has become a millionaire, advising people how to quit the habit through self-help books and clinics worldwide.
According to a spokesperson, it is not possible to tell if Mr Carr's cancer is linked to his previous smoking habit. However he 'has spent many years in smoke-filled rooms since he quit while treating smokers for their addictions'.
The spokesperson also pointed out that Mr Carr is convinced that 'he would have been dead 20 years ago' had he not given up smoking in 1983.
"Since I stopped smoking more than 23 years ago, I have been the happiest man in the world - I still feel the same way", Mr Carr said following his diagnosis.
