Seven habits that lead to happiness in old age

Based on the Harvard Medical School’s eighty-year study of people over the decades:

As the participants in the Harvard Study of Adult Development have aged, researchers have categorized them with respect to happiness and health. There is a lot of variation in the population, but two distinct groups emerge at the extremes. The best off are the “happy-well,” who enjoy good physical health as well as good mental health and high life satisfaction. On the other end of the spectrum are the “sad-sick,” who are below average in physical health, mental health, and life satisfaction…

Using data from the Harvard study, two researchers showed in 2001 that we can control seven big investment decisions pretty directly: smoking, drinking, body weight, exercise, emotional resilience, education, and relationships. Here’s what you can do about each of them today:

Briefly:

  • Don’t smoke—or if you already smoke, quit now.
  • Watch your drinking.
  • Maintain a healthy body weight.
  • Prioritize movement in your life by scheduling time for it every day.
  • Practice your coping mechanisms now. This means working consciously to avoid excessive rumination, unhealthy emotional reactions, or avoidance behavior…
  • Keep learning. More education leads to a more active mind in old age, and that means a longer, happier life… For example, that can mean reading serious nonfiction as part of a routine to learn more.
  • Cultivate stable, long-term relationships now… Find people with whom you can grow, whom you can count on, no matter what comes your way.

Each one has more detail in the article. And, “According to the Harvard study, the single most important trait of happy-well elders is healthy relationships.” 1,200 words, easy and clear reading: https://www.theatlantic.com/family/archive/2022/02/happiness-age-investment/622818/.

Dementia risk is falling at every age. Across wealthy countries, dementia risk has dropped around 13% per decade since the late 1980s, helped by better blood pressure control, lower cholesterol, less smoking and more education. This feels surprising, because dementia cases are rising as populations age, even as age-specific risk falls. We aren’t as helpless as we think either – a 2024 Lancet commission estimated that up to 45% of dementia could be prevented or delayed by tackling 14 risk factors. Vox

Three ideas for lowering electricity costs

Compared with the cost of consumer goods, which have been rising rapidly over the past few years, electricity prices are climbing even faster, an estimated 13 percent nationwide since 2022…. In 1890, a kilowatt-hour was $9.48 on average nationwide in today’s dollars; by 1950, it had dropped to 41 cents and, by 1990, to 21 cents. But recently, this century-long trend has reversed in many states; utilities are failing to keep prices low.

(1: Reduce mid-day prices:) In places with a lot of solar, including California, some installations are producing more energy than is being consumed, so some power is being wasted. If people shifted more of their electricity use toward the middle of the day, the grid’s overall costs would go down, because demand would decrease in later hours, when prices are the highest.

And the easiest way to nudge people toward using that midday power is to make it cheaper—or even free… This will give people a reason to charge their electric vehicles, use heat pumps to precool or preheat their homes and water, and store more clean electricity in batteries when cheap energy is abundant.

(2: Reduce prices by removing excess construction:) Legislators could trim these profits directly by more closely aligning utilities’ guaranteed rates of return with their actual costs…. Right now, a utility could make tens of millions of dollars on, say, putting a transmission line underground, because those that operate as monopolies (that is, most of them) can charge customers for almost every dollar spent expanding the transmission-and-distribution system—plus a profit. So more spending equals more profits, a perverse incentive called “gold-plating.”

(3: Charge all taxpayers and/or fossil fuel companies for climate-change-related costs:) As wildfires rip across the West, their damages are being borne by utility customers. This is a major reason that costs in California are so high. To take one example, the 2017 Thomas Fire created $2.4 billion in liabilities for Southern California Edison, which sparked the fire; its customers (myself included) are now on the hook for two-thirds of those costs. (The company, like PG&E, posted record profits last year.)… Passing on these climate costs to ratepayers is not the only way of dealing with them. Hawaii’s legislature decided to limit the local utility’s liability for the deadly Maui fires and to use state funds to compensate survivors. Policy makers can also keep utilities from making a profit on wildfire mitigation and other grid-hardening costs, as California has recently done.

Good news from Fix the News:

The disaster that wasn’t: how the capital city of Chad didn’t flood. Sometimes tracking stories of progress means reporting on disasters that didn’t happen. Take Chad: after severe flooding hit the capital, N’Djamena, in 2022, the country cleared and repaired 350 km of drains, deployed 12 mobile pumps and trained a lot a lot of municipal teams and drainage crews. 

When even bigger floods happened in 2024, the city remained largely unharmed, and pumps and drainage crews kept water out of neighbourhoods hit hardest two years earlier. Sometimes preparation and policy works, people! World Bank

From Fix the News, how Colombia ended its sixty-year civil war: https://fixthenews.com/p/how-to-end-a-war-lessons-from-nobel. 4,300 words:

Everyone thought peace was impossible. All my predecessors failed. But when we began planning very carefully, learning from other peace processes, what worked and what didn’t, we were able to create the necessary conditions for success.

And I think this is a lesson for the rest of the world. In the past 15 years, it is the only peace process in which the UN, which is now under fire, was instrumental and effective. At the beginning of this century, Colombia was considered a failed state. Eighteen years later, it was the country in Latin America with the best indicators in poverty reduction, inequality reduction, environmental conservation, and job creation. The lesson of how this can be done from a position of real difficulty is one that other countries can use. It is possible, through leadership and perseverance.

AI “voice cloning” scams

Americans lost more than $893 million to AI-related scams last year, including voice cloning attacks along with AI-generated phishing emails, romance scams and other hoaxes, according to the Federal Bureau of Investigation.

The article covers how AI voice scams work, and how to protect yourself:

Targets who receive these types of calls should try contacting their loved one through other means, such as via a text message, calling them on another person’s phone or reaching out to someone who would know where they are….

Families or coworkers can also establish a precautionary “code word” that can be used to verify each other’s identity. It should be a word or phrase that only a small group of people know and isn’t discoverable online.

…Let’s end with a lightning round of undiluted good news from the United States:

  • Why overdose deaths in the US are falling (it’s not because of the war on drugs).

  • Also in Texas (by far the country’s largest energy market), clean energy has overtaken fossil fuels.
  • Virginia becomes the first southern state to pass paid family and medical leave.
  • Virginia has also banned the sale and manufacture of certain semi-automatic firearms, joining 11 other states.
  • Oklahoma becomes the 17th state to ban child marriage. There has been a sea change regarding the issue in the US over the past decade.
