Don't need to get rants about this, but the context is that of a diabetic hypo. For those of you who don't know what this is, it's a lack of blood sugar caused by an excess of insulin, usually because the diabetic in question hasn't had a dose of sugar (read 'meal') at the appropriate point after an injection, or has engaged in an activity that has used more blood sugar than the insulin was supposed to have balanced.
The commentators may not know that the early symptoms of a hypo is similar to that of a drunk (probably due to the same reason ... brain functions shutting down). This means that the sufferer's judgement is impaired. If the person is in a 'zone' (for example .. In the middle of a job) they may judge that there is enough time to finish the job and then get some sugar ... and that judgement may be wrong.
As someone who had a diabetic in the family that phone conversation was very familiar. The '60' in this conversation is less than 60mg/dL of blood sugar and yeah, at this point the person is still rational but really really needs to get some sugar. Myfamily would often detect that my mother was going hypo well before she knew herself. She would respond to 'mum, take some sugar' (or if she was particularly advanced, "mum, take some sugar NOW") even though she herself didn't feel the need, and I suspect the son in the article hadn't realised the need himself.
I would agree that this remote alarm to family etc shouldn't be the first line of support. However, I can see it being a useful tool to help diabetics manage their condition. As I've pointed out above, families, friends and neighbours can be a great help, but the problem arises when they are not there. I've come back home to find my mother in a coma because she hadn't realised she was going hypo and there was no-one around to help.
So to all those who call this lunacy, shouldn't be implemented etc ... you're entitled to your opinion but as someone who had to deal with a family member with type 1 diabetes ... I think it's a great idea.
