Can the AI arms race be stopped?
America will struggle to make the technology safe while staying ahead of China
Markets are waking up to the rich world’s reckless borrowing
Governments are still, alas, asleep
In praise of Democrats’ disunity
Republicans show that party unity is overrated
How AI is creating jobs
The apocalypse is postponed. A mini boom is at hand
Why schoolchildren are getting dimmer
Machines are getting brighter; teenagers are not
The age of the orator
The transmission of ideas is moving away from text and back to the spoken word
When the five sleep factors were collapsed into binary categories of low risk vs. high risk (reference group), early chronotype, adequate sleep duration, free of insomnia, and no frequent daytime sleepiness were each independently associated with incident CVD, with a 7%, 12%, 8%, and 15% lower risk, respectively (Table 
Cardiovascular disease (CVD), including coronary heart disease (CHD) and stroke, is among the leading causes of mortality globally.
In our own study of more than 7,000 middle-aged to older adults in the U.K., published in 2019 in Brain Imaging and Behavior, we demonstrated that people who spent more time engaged in moderate to vigorous physical activity had larger hippocampal volumes. Although it is not yet possible to say whether these effects in humans are related to neurogenesis or other forms of brain plasticity, such as increasing connections among existing neurons, together the results clearly indicate that exercise can benefit the brain’s hippocampus and its cognitive functions.
Technologists, particularly those who make consumer products, will have a strong influence over how we’ll live tomorrow. By treating older adults not as an ancillary market but as a core constituency, the tech sector can do much of the work required to redefine old age. But tech workplaces also skew infamously young. Asking young designers to merely step into the shoes of older consumers (and we at the MIT AgeLab have literally developed a physiological aging simulation suit for that purpose) is a good start, but it is not enough to give them true insight into the desires of older consumers. Luckily there’s a simpler route: hire older workers.
