NEW SCAN GOES BEYOND BIRTHDAY CANDLES FOR YOUR TRUE AGE

Friday, September 8, 2023

Chronological age doesn’t tell the full story. Now a 3D camera and artificial intelligence is revealing what makeup, dark sunglasses, and plastic surgeons try to hide.

That’s your so-called biological age, reflecting the health of your cells and organs and your environment, diet, and exercise habits.

And that age (shown in the face of an aging woman above) can vary widely from the number of candles on your birthday cake.

—How to take care of your aging brain?

HOW WE GOT THE PHOTOS

LAST GLIMPSE

The only one: The fish pens float in 240-feet deep, strong Hawaiian waters. Inside each, 100,000 kanpachi (pictured above) await to be harvested; outside, seals, sharks, and giant trevally are abundant, and healthy coral grows. This unique fish farm could feed America’s appetite for protein. But the question stands: Why does only one exist?

We asked, you responded: Thanks for a flood of notes from readers on our question about rising COVID and home tests. For the most part, respondents are stocked with a few to as many as 50 home tests as COVID infects more of us again. Laurie Gordon writes that she has used some of her modest stock “and shared some with family who did not have access.” Here’s hoping you don’t have to make tough choices.
