I went to the Doc's just before Christmas, had the glucose blood test (I don't know the proper term for it), which came in 3 points below being classed as type 2 diabetic.
Doc says change diet and exercise. Diet is difficult after a lifetime of sweets but I think I'm improving, although I reckon it'll be about 5 years before I'll be allowed near sweets again, lol.
As for exercise, I tried walking but found that quite boring and susceptible to the weather so I've taken to walking (and sometimes running) in the local pool. Running in water does terrible things to leg muscles, believe me.
Christmas is never the best time to diet, but have managed to ditch 2 kilos over the last 3 weeks with hopefully more to follow.
Time will tell.
