My doctor said to me one day, some years back, that if I continued to smoke and do all the other unhealthy things I was doing, my chances of having a heart attack or stroke during the next 10 years was 1 in 5. I checked on the internet and she was absolutely right!
I decided straight away to try harder to give up smoking which was my biggest risk factor. I succeeded and haven't smoked for 14 or 15 years.
