Primary prevention of ill health in older people using IoT?
Apply a smart tatoo of a rose to all 30 year olds, as they get closer to fifty it will turn darker and eventually black at fifty. Whereupon it will broadcast a 'kill me' signal to the farty police, at the same time it will pipe 24/7 noe direction music interspersed with Justin Bebe directly to the aural centre of the brain, if the farty police don't get them they will commit suicide soon enough.
No old people, no ill health in them.
I'm 65 but I don't live in the UK let alone Cambridge.
