@danielcawrey... The unfortunate reality of privacy rears its ugly head. It is, or should be, a big concern and no doubt someone will find a way to bring it to the forefront. It will be interesting how this is handled.
I think this stuff is cool and makes it fun to stay healthy. An easy way to record and track activity and blood pressure makes people more inclined to monitor it. I think Google will have a little more success this time around.
