From a New York Times online article:
If one geriatrician can care for 700 patients with complicated medical needs, as a federal model estimates, then the nation will need 33,200 such doctors in 2025. It has about 7,000, only half of them practicing full time. (They’re sometimes confused with gerontologists, who study aging, and may work with older adults, but are not health care providers.)
Geriatrics became a board-certified medical specialty only in 1988. An analysis published in 2018 showed that over 16 years, through academic year 2017-18, the number of graduate fellowship programs that train geriatricians, underwritten by Medicare, increased to 210 from 182. That represents virtually no growth when adjusted for the rising United States population.
“It’s basically stagnation,” said Aldis Petriceks, the study’s lead author, now a medical student at Harvard.
Hundreds of miles south of Japan’s main islands, in the East China Sea, is a Jurassic Park of longevity, with a higher percentage of centenarians (people who live to 100 years old) than anywhere else on Earth. 
…the researchers demonstrated that the biggest drop in cognitive ability occurs at the slightest level of hearing loss — a decline from zero to the “normal” level of 25 decibels, with smaller cognitive losses occurring when hearing deficits rise from 25 to 50 decibels.
Aging, Duration, and the English Novel argues that the formal disappearance of aging from the novel parallels the ideological pressure to identify as being young by repressing the process of growing old. The construction of aging as a shameful event that should be hidden – to improve one’s chances on the job market or secure a successful marriage – corresponds to the rise of the long novel, which draws upon the temporality of the body to map progress and decline onto the plots of nineteenth-century British modernity.
o finds himself wondering if growing old in Paris might be the perfect antidote to the drama he left behind in New York. Unflinching, witty, and urbane as ever, Louis Begley delivers a spot-on satire of the world of New York’s aging elite, and uncovers the unexpected delights a late-in-life change can offer.
‘Successful Aging’ uses research from developmental neuroscience and the psychology of individual differences to show that sixty-plus years is a unique developmental stage that, like infancy or adolescence, has its own demands and distinct advantages. Levitin looks at the science behind what we all can learn from those who age joyously, as well as how to adapt our culture to take full advantage of older people’s wisdom and experience. Throughout his exploration of what aging really means, Levitin reveals resilience strategies and practical, cognitive enhancing tricks everyone should do as they age.
“As the number of people over 50 grows, that age cohort is transforming markets and sparking new ideas, products and services across our economy,” AARP CEO Jo Ann Jenkins says. “And as people extend their work lives, they are fueling economic growth past the traditional retirement age.
More schools are building or planning senior-living facilities on or near campus to cater to baby boomers who view college as a stimulating alternative to bingo at an archetypal retirement home.
