Like a lot of high school students, Kevin Tran loves superheroes, though perhaps for different reasons than his classmates. “They’re all insanely smart. In their regular jobs they’re engineers, they’re scientists,” said Tran, 17. “And you can’t do any of those things without math.” Tran also loves math.

Health officials released in December the first nationally representative estimate of how many U.S. adults have chronic fatigue syndrome: 3.3 million. The Centers for Disease Control and Prevention’s number is larger than previous studies have suggested, and is likely boosted by some of the patients with long COVID.

But even with the large increase, U.S. life expectancy is only back to 77 years, 6 months — about what it was two decades ago. Life expectancy is an estimate of the average number of years a baby born in a given year might expect to live, assuming the death rates at that time...
