Pardon? Like sensitive electronic equipment, ears can be easy hurt but also easily enhanced technologically

Damage to hair cells or to the nerve synapses they’re attached to is the most common source of hearing loss. Aging and noise are the leading causes; among the others are the chemotherapy drug cisplatin, the aminoglycoside family of antibiotics, and various autoimmune diseases, including the one that deafened (but didn’t silence) Rush Limbaugh. Corey showed me another electron micrograph, from the ear of a mouse that had been exposed for two hours to sound as intense as that experienced by someone using a chainsaw. The cilia looked like tree trunks thrown around by a tornado.

Hair cells can recover if a noise isn’t too loud and doesn’t last too long, but permanent injuries accumulate. A widely cited damage threshold for sustained exposure is eighty-five or ninety decibels. (The human hearing range is so wide that it has to be described logarithmically to keep the numbers from becoming unmanageable: every ten-decibel increase represents a tenfold increase in sound energy.) An unsettling number of everyday activities lie at or above the danger line, including lawn-mowing, motorcycle-riding, rock-concert-going, Shop-Vac-ing, milkshake-making, subway-riding, and power-tool-using. “Most carpenters have lost a lot of hearing by the time they’re fifty,” Corey said. “I’m sometimes around construction sites, and I often pass out ear protection.”

Baths Versus Exercise, a Study in Calories – The Atlantic

April 16, 2017

Baths vs #Exercise, a Study in Calories In 1hr, burn 60 in a hot bath vs ~550 on a bike ride. Laziness has benefits!

The researchers set out to see how exposure to heat can alter the molecules in our bodies. There were only 14 people (all men) in the study. They took hour-long baths at 104-degrees Fahrenheit and did burn calories, which were also measured, since energy is required to keep our cores around 98.6-degrees. But the men only burned an average of about 61 calories more than if they had been sitting at room temperature. When they exercised on a bike for the same amount of time, they burned between 515 and 597 calories.

Silicon Valley’s Quest to Live Forever

SV’s Quest to Live Forever Cal. restriction to #Singularity: Immortalists v Healthspanners, Meat Puppets v RoboCops


“Immortalists fall into two camps. Those who might be called the Meat Puppets, led by de Grey, believe that we can retool our biology and remain in our bodies. The RoboCops, led by Kurzweil, believe that we’ll eventually merge with mechanical bodies and/or with the cloud. Kurzweil is a lifelong fixer and optimizer: early in his career, he invented the flatbed scanner and a machine that reads books aloud to the blind. Those inventions have improved dramatically in subsequent iterations, and now he’s positive that what he calls “the law of accelerating returns” for human longevity is about to kick in.”

“The battle between healthspanners and immortalists is essentially a contest between the power of evolution as ordained by nature and the potential power of evolution as directed by man. The healthspanners see us as subject to linear progress: animal studies take the time that they take; life sciences move at the speed of life. Noting that median life expectancy has been increasing in developed nations by about two and a half years a decade, Verdin told me, “If we can keep that pace up for the next two hundred years, and increase our life spans by forty years, that would be incredible.”

The immortalists have a different view of both our history and our potential. They see centuries of wild theorizing (that aging could be reversed by heating the body, or by breathing the same air as young virgins) swiftly replaced by computer-designed drugs and gene therapies. Bill Maris said, “Health technology, which for five thousand years was symptomatic and episodic—‘Here are some
leeches!’—is becoming an information technology, where we can read and edit our own genomes.”

Many immortalists view aging not as a biological process but as a physical one: entropy demolishing a machine. And, if it’s a machine, couldn’t it be like a computer?

“And yet. Last year, the geneticist Nir Barzilai hosted a screening of a documentary about longevity, and afterward he posed a question to the three hundred people in the audience. He told me, “I said, ‘In nature, longevity and reproduction are exchangeable. So Choice One is, you are immortalized, but there is no more reproduction on Earth, no pregnancy, no first birthday, no first love’—and I go on and on and on.” He laughed, amused by his own determination to load the dice. “ ‘Choice Two,’ I said, ‘is you live to be eighty-five and not one day sick, everything healthy and fine, and then one morning you just don’t wake up.” The vote was decisive, he said. “Choice One got ten or fifteen people. Everyone else raised their hands for Choice Two.”

This wish to preserve life as we know it, even at the cost of dying, is profoundly human. We are encoded”

Fighting Hearing Loss From the Crowd’s Roar

Fighting #Hearing Loss From the Crowd’s Roar Silent, cumulative loss from the effect of loud sounds over a lifetime

Ears are deceptive. Even if they seem to recover from the muffling, ringing and fullness after a rousing game, they don’t really recover. It’s not just the tiny sensory cells in the cochlea that are damaged by noise, Dr. Liberman said, but also the nerve fibers between the ears and the brain that degrade over time.
Too much noise causes not just partial deafness, which usually starts with trouble hearing in background noise, but an assortment of poorly-understood auditory abnormalities. These include tinnitus, or ringing in the ear, and hyperacusis, a sensitivity or intolerance to sound, sometimes with ear pain.

Easy comparison of smart care v choice plans


The Aetna Smart Care Plan provides quality care along with an expansive network of medical care facilities for your healthcare coverage.
How It Works: After you meet your deductible, the plan pays 90 percent for most covered in-network services up to the annual out-of-pocket maximum. Once the annual out-of-pocket maximum has been reached, the plan pays 100 percent.

The Aetna Choice POS II medical plan provides coverage for a wide range of medical expenses. The plan also provides coverage for certain preventive and wellness benefits.
How It Works: Through Aetna Choice, you pay for care, except preventive services, until you meet the deductible which varies based on the plan you choose. Once you’ve reached your deductible, your plan pays for 90 percent for most covered services and you pay 10 percent until you reach the annual out-of-pocket maximum.
