Today, if you wish, you can go get a staggering amount of granular data about your health without your doctor’s involvement. All on your own, you can get an MRI of your entire body, a CT of your coronary calcium, an ultrasound of your blood vessels, and maybe someday an immersion ultrasound in a spa. |

As a radiologist, a doctor specialized in the alchemy of turning information into health, I translate data hidden in images into words that motivate behavior to promote healthier, longer lives. Because it is central to what we do, radiologists have grappled for decades with the question of whether and how information improves health. It turns out to be surprisingly complicated. |

Norah O’Donnell at CBS News talks with grief coach Kate Doerge about why grief isn’t something you “move on” from—and how to keep reaching for joy anyway. The cost of employer-provided health insurance is going to keep rising. Factors including more chronic disease, the use of GLP-1s, and rising demand for health services are driving the increase, Adriel Bettelheim reports for Axios.
