What is the best way to use technology to promote healthy aging in older people? For example, if I was over 70 and living alone but had access to technology, what would be the best case scenario I could put myself it. Should I monitor my weight, steps and blood pressure everyday? Should I wear a device that can pick up anomalies in my movement that could predict illness or falls? I am talking about more than a personal alarm that i can ring when in trouble.
