A good friend of mine, Caroline, a master hair stylist in San Francisco, was working on my hair late last year when the gossip set in.\n\t\u201cWow, your body and mental stress levels went through hell in the last few months,\u201d she said.\n\t\u201cHow did you know?\u201d I asked.\n\tA few months prior, I had a near-death blood infection that led to multiple emergency room visits, lengthy hospital stays, relapses and powerful antibiotics given intravenously for months.\n\t\u201cWell, you\u2019re missing staggered lengths and your hair feels like straw,\u201d she said.\n\tCaroline went on to explain that hair typically grows half an inch every month. During that stressful period of my life, I shed hair. By the time Caroline cut it, I had new growth but was missing noticeable lengths of healthy hair.\n\tNasty side effects from the powerful antibiotics, coupled with poor nutrition, also meant my body had to divert energy. My hair was left by the wayside, which led to hair loss, dry hair and more white hair.\n\tMy hair now tells the story of what I consider the lost season of my life.\n\tWhat does this have to do with technology? Absolutely nothing \u2013 and that\u2019s the point.\n\tSo much is made of big data, analytics software, mobile apps that secretly (and not-so-secretly) harvest personal information, such as where you\u2019ve been, what you\u2019ve done and how you like to spend your money.\n\tBut valuable information doesn\u2019t always come in the form of digital data. Sometimes, it\u2019s a knowledgeable person observing the natural state of things. You can bet there's no app for that.\n\tWhite hair aside, I find it both refreshing and comforting that software really can't provide that kind of insight.
