The Up's sensors collect data about how much you've been sleeping and how much you've been moving. That data is then fed into a smartphone app, which also takes in information about your meals. (You enter meal data manually, in part by taking pictures of what you've eaten.) Based on all that information, the smartphone program provides "nudges" meant to help you live healthier, day by day. For example, if you haven't slept much, when you wake up the app might suggest a high-protein breakfast and an extra glass of water.

Do we not spend enough time navel-gazing? Enough time on FB, twitter telling the world what 'we' are constantly doing, as if anyone even asked...and maybe people don't respond enough, so now we need to design more 'me, myself and I' tools...PJ
