There is nothing like a near-death experience to make you acutely aware of how much we rely on medicine and the healthcare system. I suffered a massive heart attack in March 2012 and nearly died. The doctors saved me. Since that terrifying event, I have tracked developments in technology, medicine, and wellness carefully. All along, I wondered why so much health care aimed at saving us after we fell ill rather than at keeping us healthy and spotting the problems well in advance. People in the healthcare sector call such an approach wellness care, or preventive medicine.
