Health Insurers Are Vacuuming Up Details About You — And It Could Raise Your Rates

With little public scrutiny, the health insurance industry has joined forces with data brokers to vacuum up personal details about hundreds of millions of Americans, including, odds are, many readers of this story.

The companies are tracking your race, education level, TV habits, marital status, net worth. They’re collecting what you post on social media, whether you’re behind on your bills, what you order online. Then they feed this information into complicated computer algorithms that spit out predictions about how much your health care could cost them.

How concerned about this should we all be?

Patient advocates warn that using unverified, error-prone “lifestyle” data to make medical assumptions could lead insurers to improperly price plans — for instance, raising rates based on false information — or discriminate against anyone tagged as high cost. And, they say, the use of the data raises thorny questions that should be debated publicly, such as: Should a person’s rates be raised because algorithms say they are more likely to run up medical bills? Such questions would be moot in Europe, where a strict law took effect in May that bans trading in personal data.

Off Your Mental Game? You Could Be Mildly Dehydrated

How severe does dehydration have to be to affect us?

A growing body of evidence finds that being just a little dehydrated is tied to a range of subtle effects — from mood changes to muddled thinking.

Moreover:

As we age, we’re not as good at recognizing thirst. And there’s evidence that older adults are prone to the same dips in mental sharpness as anyone else when mildly dehydrated.

So how much water do we need every day?

A panel of scholars convened several years ago by the National Academies of Sciences, Engineering and Medicine concluded that women should consume, on average, about 91 ounces of total water per day. For men, the suggested level is even higher (125 ounces).

The phrase total water means that water from all sources counts: fruits, vegetables soup, smoothies, and, yes, even your morning cups of coffee or tea.

And remember that by the time you feel thirsty, you’re already beyond the point of mild dehydration. According to the article, an hour of hiking in the heat or a 30-minute run might be enough to cause mild dehydration.

Ask yourself these questions before saying “yes” or “no” to anything

Although this article is aimed at people in business, it can also prove useful for others.

most of us are completely unaware of why we are saying “yes” or “no.” For those who suffer from the disease to please, saying “yes” often comes from the fear of being disliked and the guilt for putting your own agenda ahead of someone else’s desire for your time and attention. Those who may be considered “no” people often say no out of fear of failure. What if I don’t like it? What if I’m not good at it? Others say “no” simply because they have set boundaries and haven’t left any room in their lives for spontaneity and unexpected growth.

The article offers advice for how to decide whether to say “yes” or “no.” Also included are links to several related articles.

The theory of mind myth

Theory of mind is the psychological term for our belief that other people have emotions, beliefs, intentions, logic, and knowledge that may differ from our own.

That we have a folk psychology theory of other minds isn’t surprising. By nature, we are character analysts, behavioural policemen, admirers and haters. We embrace like minds, and go to war against contrarians. Mind-reading is our social glue, guiding virtually all of our daily interpersonal interactions. When trying to decide whether or not a potential gun owner is prone to violence, a mental patient is suicidal, or a presidential candidate is truthful, we are at the mercy of our thoughts about others.

But, argues neurologist Robert Burton, former associate director of the department of neurosciences at the University of California, San Francisco Medical Center at Mount Zion, “Even experts can’t predict violence or suicide. Surely we’re kidding ourselves that we can see inside the minds of others.”
