metabolism aging old age

  • Ripped musclesThe metabolism is every drop of chemistry needed to keep the body going. And the bigger the body - whether that is ripped muscles or too much belly fat - the more energy it will take to run.
  • The study, published in the journal Science, found four phases of metabolic life:birth to age one, when the metabolism shifts from being the same as the mother's to a lifetime high 50% above that of adults a gentle slowdown until the age of 20, with no spike during all the changes of pubertyno change at all between the ages of 20 and 60a permanent decline, with yearly falls that, by 90, leave metabolism 26% lower than in mid-life
  • Other surprises came from what the study did not find. There was no metabolic surge during either puberty or pregnancy and no slowdown around the menopause.

  • "When people talk about metabolism, they think diet and exercise - but it is deeper than that, we are actually watching your body, your cells, at work," Prof Herman Pontzer, from Duke University, told BBC News."They are incredibly busy at one year old and when we see declines with age, we are seeing your cells stopping working."
  • Prof Tom Sanders, from King's College London, said: "Interestingly, they found very little differences in total energy expenditure between early adult life and middle age - a time when most adults in developed countries put on weight. "These findings would support the view that the obesity epidemic is fuelled by excess food energy intake and not a decline in energy expenditure."

FBI arrests spotlight lessons learned after Charlottesville (opinion) - CNN - 0 views

  • On Thursday, the FBI arrested three men, Patrik J. Mathews, 27, Brian M. Lemley Jr., 33, and William G. Bilbrough IV, 19, with firearms charges, and they had plans, an official said, to attend a Virginia pro-gun rally. This followed Virginia Gov. Ralph Northam's declaration of a temporary state of emergency after authorities learned that extremists hoped to use the anti-gun control rally planned next Monday -- Martin Luther King, Jr. Day -- to incite a violent clash.
  • These arrests add to mounting evidence that a decades-old and violent white-power movement is alive and well, perhaps even gaining strength. White power is a social movement that has united neo-Nazis, Klansmen, skinheads, and militiamen around a shared fear of racial annihilation and cultural change. Since 1983, when movement leaders declared war on the federal government, members of such groups have worked together to bring about a race war.

  • Silver linings aside, it will take many, many more instances of coordinated response to stop a movement generations in the making. In more than a decade of studying the earlier white power movement, I have become familiar with the themes of underground activity that are today clearly drawing from the earlier movement. In the absence of decisive action across multiple institutions, a rich record of criminal activity and violence will continue to provide these activists with a playbook for further chaos.
  • The Base, furthermore, is what experts call "accelerationist," meaning that its members hope to provoke what they see as an inevitable race war. They have conducted paramilitary training in the Pacific Northwest. Both of these strategies date back to the 1980s, when the Order trained in those forests with hopes of provoking the same race war.
  • One of the men arrested Thursday was formerly a reservist in the Canadian Army, where he received training in explosives and demolition, according to the New York Times. This kind of preparation, too, is common among extremists like these. To take just a few representative examples, in the 1960s, Bobby Frank Cherry, a former Marine trained in demolition, helped fellow members of the United Klans of America to bomb the 16th Street Birmingham Baptist Church, killing four black girls.
  • This news out of Virginia shows that there is a real social benefit when people direct their attention to these events -- and sustain the public conversation about the presence of a renewed white-power movement and what it means for our society.

Year-long resolutions don't work. Here's how to make 12 'micro-resolutions' instead - CNN - 0 views

shared by katherineharron on 19 Jan 20 - No Cached
  • A mini- or micro-resolution is any behavior you commit to for four weeks. And even longer-term goals to, say, eat better or learn a new skill, can be broken down into more achievable goals on the way. Before you can land on Mars, focus on landing on the moon.
  • To create your micro-resolutions, you can start by thinking of 12 "bad" habits or indulgences you'd like to cut back on or give up entirely. This is what I did last year for what I called my "Year of Abstinence." My plan was to learn something about myself through self-denial, and it worked: I gave up alcohol, sweets, television and nine other things, but just for a month each. The mini-resolutions were as positive as they were eye-opening.
  • In order to simply increase my own, general awareness, every day in January my goal was to notice something new. I kept my eyes open, looked a bit longer, stopped to read the history markers, noticing buildings or took a different route than normal -- small ways to avoid sleepwalking through life.

  • Sleep is tied to many positive health outcomes according to a constant stream of medical research, much of which recommends more than seven hours a night. My goal was to sleep eight hours each night, and for the first two weeks of the month I tried and failed. I didn't manage it once. It started stressing me out.Wake up, people: You're fooling yourself about sleep, study says I did get more sleep than I would have otherwise because I prioritized getting to bed earlier. But between work, training for a marathon, kids' bedtimes and evening plans, my life was not conducive to that schedule. But since I'm making up the rules (and you make up yours) I gave up on sleep.
  • Research ties nature exposure to both longevity and happiness, so I made it a goal to commune with nature every day. This could include a run through a park, stopping to hug a tree (which I did at least once), or watching a convoy of ants cross a sidewalk.
  • Another super-habit for mental and physical health, I made an effort to incorporate meditation in some form -- whether it was 10 breaths, 30 minutes, guided, formal, mantra-led, what have you -- every day.
  • To complement March's switch-up, my plan for June was the same split: 8 hours of sleep at night and active listening with the kids. I didn't think I could pull a straight fortnight of great sleep, so my aim was for 15 nights of sleep and 15 days of not doing something else while listening.
  • At CNN, I sit near a constant pile of sweets. And that combined with my weakness for them equals a snacking problem. So in July, my goal was to make fresh fruit my standard snack of choice and eat at least one piece or serving a day. And more water -- at least a pint before coffee in the morning.
  • In August I attempted to not stay seated for more than 30 minutes during waking hours. Recent research has associated a number of poor health conditions with a sedentary lifestyle. And while no one can definitively say how much sitting is bad for us, moving every 30 minutes has emerged as a good guideline.
  • My commitment in September was 15 minutes of some form of creative writing each day, almost entirely in a writer's notebook that I've had since college. It's full of random dialogue, lists and story plots, and I used to write in it often but not so much in recent years.
  • Read a novel. That was it. Given that I mainly read non-fiction, this idea seemed rather novel (sorry).
  • My intention was to make a daily gesture of gratitude -- an emotional state with its own positive health outcomes -- and I quickly fell behind. I decided instead (because, again, I make up the rules) to make the goal a total of 30 thank yous, one for each day of the month, and I managed to cram them all in.
  • In another attempt to combat unhealthy snacking, my final goal for 2019 was to convert my diet into one filled with non-processed, whole foods. Carrots and peanut butter instead of donuts; almonds instead of old Halloween candy -- you get the idea. I also declared my intention to track my progress and give myself a daily score.

Binge drinking: US adults are drinking even more, study says - CNN - 0 views

  • Adults in the United States who binge drink are consuming even more alcohol per binging episode, according to a new study published Thursday by the US Centers for Disease Control and Prevention. Researchers analyzed data from the Behavioral Risk Factor Surveillance System over a six-year period and discovered that the annual number of binge drinks among adults who reported excessive drinking jumped on average from 472 in 2011 to 529 in 2017. That's a 12% increase.It's not just college kids. A new study says older adults binge drink, tooThe CDC defines binge drinking as five drinks or more for men or four or more for women on a single occasion. Binge drinking has serious health risks, according to the CDC, including car accidents, domestic violence, STDs, unintentional pregnancy, stroke, heart and liver disease.
  • In 2017, the number of binge drinks pear year among adult binge drinkers ranged from 320 per year in Massachusetts to 1,219 in Wyoming. The number of drinks among those who reported binge drinking increased in nine states -- Idaho, Indiana, Maine, Montana, New Jersey, New York, North Dakota, Ohio and Virginia -- while the number of drinks decreased significantly in Massachusetts and West Virginia.

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

  • “These are heartless sadists who have put in countless hours of backstabbing and forsaken all ethical constraints in order to bolster their own power, and yet time and time again they are denied a place at the top of the corporate ladder simply because of the color of their skin,” she continued.According to the report, even when companies were presented with numerous highly qualified minority candidates with no moral compass and a history of increasing earnings by knowingly rushing an unsafe product to market or outsourcing thousands of manufacturing jobs to overseas sweatshops, the top-tier positions still tended to be awarded almost exclusively to deceitful, empathy-devoid whites.
