In a fascinating new study our ideas of old age are challenged..

Professor Tom Kirkwood has demolished a string of misconceptions about the ageing process with a groundbreaking study into the health of more than 1,000 older people in the 85-plus generation. “Its a myth that they are bowls of misery, unhappy with their lot, and always going on about ailments,” he insists. “Four out of five of them actually think they are doing pretty well.”His study, the largest of its kind ever undertaken, has proved revealing on several fronts. For a start, people in the 85-plus range are generally much happier, and more independent, than is generally realised. Remarkably, 80% of a group carefully selected by the Kirkwood team – a fair sample of the UK population of this age – need little care. Around the same number rate their quality of life either good or excellent.On the downside, 20% need either regular daily help or critical 24-hour care. All of which might be almost manageable for the state, and for society, if this age range was static. But, as the amiable Kirkwood never tires of reminding questioners, the 85-plus group is now the fastest-growing segment of the population.

..Of course, this has huge implications for the cost of caring. Revealingly, in tracking 17 activities of daily living among survey participants – from dealing with finances to cooking and shopping – researchers found that men fared better than women; a third managed all 17 without help, compared with a sixth of women. Although women live, on average, five to six years longer than men, the study has found that their disabilities become greater with age.

Hans Rosling had a question: Do some religions have a higher birth rate than others — and how does this affect global population growth? Speaking at the TEDxSummit in Doha, Qatar, he graphs data over time and across religions. With his trademark humor and sharp insight, Hans reaches a surprising conclusion on world fertility rates.

In Hans Rosling’s hands, data sings. Global trends in health and economics come to vivid life. And the big picture of global development—with some surprisingly good news—snaps into sharp focus.

We’ve been to the moon, we’ve mapped the continents, we’ve even been to the deepest point in the ocean — twice. What’s left for the next generation to explore? Biologist and explorer Nathan Wolfe suggests this answer: Almost everything. And we can start, he says, with the world of the unseeably small.

Armed with blood samples, high-tech tools and a small army of fieldworkers, Nathan Wolfe hopes to re-invent pandemic control — and reveal hidden secrets of the planet’s dominant lifeform: the virus.

How do we consume data? At TED@SXSWi, technologist JP Rangaswami muses on our relationship to information, and offers a surprising and sharp insight: we treat it like food.

With a background in economics and journalism, JP Rangaswami has been a technology innovator and chief information officer for many leading financial firms. As an advocate for open source and disruptive technologies, Rangaswami has been a leading force in the success of multiple startups, including School of Everything, Salesforce.com and Ribbit.
Information, if viewed from the point of view of food, is never a production issue. … It’s a consumption issue, and we have to start thinking about how we create diets [and] exercise.” (JP Rangaswami)

Patrice Slupowski, director of innovation at Orange France Telecom, quotes Ericsson’s CEO who predicts 50 billion connected devices by 2015. With 3 billion expected internet users, this means we will have 17 devices per connected people.

By 2015, 3 years from now we will be carrying on us sensors and other devices that produce data. What is the future of this data?
