Bill Harvey: Inspect a gadget

I do love a good gadget and recently have come across three I believe worth mentioning, each offering a different approach to health management.

The first was a new method of monitoring blood glucose levels in diabetes that does away with finger pricking. Having seen the black and blue extremities of many a diabetic caused by constant needle pricking, I have started telling people about the new Freestyle Libre. This is a small disc sensor applied to the arm where it remains for around two weeks before needing replacement. The sensor transmits a constant reading of blood sugar levels to a smart phone or even a Fitbit device and will warn the wearer whenever blood glucose approaches any dangerous levels.
