In the world of digital health, Silicon Valley-based Mindstrong stands out. It has a remarkable team and tens of millions of funding. It also has a fascinating idea--its app, based on mental functioning research, can help detect troubling mental health patterns by collecting data on person’s smartphone usage--how quickly they type, for instance.
The company’s app collects information about how people are typing and runs it through a machine learning algorithm (计算程序) to determine which data can predict their emotional state. The idea is to use that data to establish a “normal” pattern--so it can be compared with someone’s typing habits on any given day. If the habits change, slower or more anxious than normal, the app can warn a health care provider.
The promise of this technology has made Mindstrong incredibly popular since it was launched last year; already more than a dozen counties in California have agreed to apply the company’s app to patients. Does the app live up to its promise? There’s no way to tell. Almost no one outside the company has any idea whether it works, leading some experts to wonder if the technology is ready for the real world. “I wouldn’t waste all that time and money in the wild until they get sure that some of those things are as specific as they hope they are,” said Rosalind Picard, a researcher at MIT Media Lab, who is familiar with Mindstrongs work.
“It has passed the gold-standard clinical tests for depression and anxiety,” said Dr. Paul Dagum, the company’s founder. “We’re confident, and we’re already seeing some really exciting results.” Mindstrong officials said that among their most encouraging results is that its app can even predict how a person will feel next week, kind of like a weather app for your mood. “For a clinician or someone looking after a patient, they know that it could be very, very powerful,” Dagum said.

I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St. Lucie just minutes from the ocean, an uncontrollable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida’s mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.
I’m like a migratory bird (候鸟) that has lost its sense of timing and direction, my wings flapping against season.
So what makes me fly against the tide of snowbirds? The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display of colors -- first in the fall trees, and then in the lights around homes and at Rockefeller Center. Floridians decorate too, but can’t create the special feel of a New England winter.
I suppose the biggest reason why I return is to celebrate the holidays with people I haven’t seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors children excitedly open gifts on Christmas? Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch. (My wife and I spend winters at a retirement community in Ridge, and I’m grateful that I don’t have to shovel.)
While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can’t go home?
