Today at a conference at NYU I learned all about the Oura ring, that $350 health-monitoring device you wear on your finger. For example, one colleague told me that it can continually monitor your heart rate, body temperature, blood oxygen level and breathing rate. It even has a linear accelerometer.
Another colleague told me that it can also be used for family planning. When I asked her how, she explained that it can track your menstrual cycle.
I told her that you could also use a VR headset for family planning. “Why can a VR headset do that?” she asked.
“Because,” I replied, “it gives you a headache.”
