Most people in this forum seem very negative, but maybe it will get seniors back to using computers. It measures medical data like a tricorder, and my mother wastes money on diabetes test strips and is always messuring her blood pressure.. I don't really know what it measures, but cheaper medicine is always desired as medicare is broke being $45 trillion in debt.
I believe sports watches measure pulse rate already. As far as diabetes goes, I doubt Apple's watch is advanced enough to deal with that. To the best of my knowledge, you still have to stick yourself to draw blood for the blood glucose test, and hold a test strip in your urine stream to test for sugar and /or ketoacidosis.
So, unless this watch shoots spikes into your finger, or you need to hold it under you while you pee, it isn't going to do squat to monitor diabetes.
As far as saving money in medical expenses, just don't take all the tests they prescribe for you, for the sake of pleasing your doctor, avoid any tendencies toward hypochondria, and tell every other crap hole on medicare to do the same.
Oh, before I forget, save the $350.00 price of the watch, and use it toward your co-pays.
And no, the iWatch isn't anything like the imaginary "tricorder".
I have CBC, chem panels, INR, and PT tests done on a regular basis. They require 4 or 5 full vials of blood to be drawn. The iWatch won't do any of that either. It's a toy.
And BTW, Walmart sells Novalin "N", for less than $25.00 a vial.
A bit about blood pressure:
Blood pressure varies by time and activity. If someone's BP is controlled, either by medication or by nature, it really is a waste of time to keep checking it too frequently. Hypochondria, plain and simple. You drink a cup of coffee, it goes up, take some Valium, it goes down. Salty pizza, put +20 on the diastolic column. Exercise? Then the diastolic goes up dramatically, while the systolic falls quite a bit. (vasodialation at work here kids).
In the case of someone with valvular heart disease, taking BP at the arm, is virtually pointless. So, unless the iWatch is capable of cardiac catheterization, that's another huge fail.
