In this edition: Super babies, cannabis rules and listening to your body.

Better babies? Silicon Valley parents are increasingly obsessed with having smarter children. They are paying up to $50,000 for new genetic-testing services that include promises to screen embryos for IQ, while professional matchmakers are setting up tech execs with brilliant partners partly to get brilliant offspring.

The cannabis question. President Trump is considering reclassifying marijuana as a less dangerous drug, after pot companies have poured millions of dollars into Trump’s political groups. The push centers on whether marijuana should be reclassified as a Schedule III drug, which among other things would allow for additional medical research.

Eli Lilly’s Mounjaro price move. The pharma giant said it is negotiating to raise drug prices in Europe, starting in the U.K. with the weight-loss drug Mounjaro, so that it can comply with the Trump administration’s goal of bringing down prices in the U.S.

“It was nothing,” she told herself. Only it wasn’t. Wall Street Journal editor Melissa Korn tells the story of how she finally listened to her body, sought help, and saved her own life. Sometimes we want to brush off symptoms, but doctors say certain pains can signal serious risks, including blood clots.

Melissa’s story generated hundreds of comments, and she responded to many of them. Here are some of those exchanges, edited for length.

• Rahul H.: “I once delayed care because the young kids were asleep—it luckily worked out, but it’s hard for caregivers to get care for themselves.”
  MK: Indeed it is so hard! After my gallbladder situation I came up with a game plan and a list of people I’d call in case of emergency, if something else ever happened and my daughter was with me. Friends and neighbors. Of course all said yes.
• William M.: “Most people ignore symptoms because they want to remain in denial. They don’t have the ailment until they are diagnosed so they are safe as long as they don’t go to the doctor. Sounds crazy but every economist and psychiatrist knows about our predictable irrationality.” 
  MK: Absolutely. I spoke to a few psychiatrists about this exact thing. As one told me, denial is a very powerful drug.
• Roger R.: “Had a similar experience nine months after a quadruple bypass. I thought it was just indigestion and wasn’t going to notify my doctor but changed my mind. Although he said take an ambulance to the hospital, I drove. I was told it was a ‘minor’ heart attack, and after a stent was put in my whole well-being changed. As a former athlete, I had learned to ‘tough it out’ which fortunately I did not do this time.”
  MK: Thanks for sharing your story. I hated the idea of being a crybaby or somehow perceived as weak. So glad you listened to your gut as well, and I hope your healing process is going smoothly.

Baby carnivores. Rising interest in protein and concerns about ultraprocessed foods are causing some people to look at carnivore-style diets–including for their infants and toddlers. Pediatricians warn diets that focus on meat and dairy can skimp on nutrients babies need for development like vitamin C and fiber.

A pill for weight loss. Wall Street seems to have soured on the opportunity for oral versions of popular GLP-1 drugs. Eli Lilly’s shares fell last week after underwhelming results for its pill, orforglipron. Yet Lilly’s pill could still be a commercial breakthrough, not because it is more potent but because it is more accessible.

Apple Watch gets blood oxygen feature back. Some watch models will get the pulse oximetry feature back nearly two years after Apple was forced to remove the capability due to a bruising patent dispute with a rival. The feature measures oxygen saturation in blood similar to the clamshell devices that doctors slip on patients’ fingers.
