All part of getting older, except when it was the first signs of diabetes, along with a couple of midge bites that took months to heal and restless, jumpy legs. Since getting it I’ve learned that the TV and Media portrayal that diabetes is a big fat biffa watching telly thing is fairly misleading.
If you’re unlucky enough to have the genes for a pancreas that gives up in your 40s then a high carb diet will be bad no matter how active – although being active you’ll probably fair better.
