The Secret Life of Trader Joe

I came across this article a few years ago when it first came out, but I have often – several times a year, at least – referenced it to my friends.  It’s always when someone talks about how home-grown the brand is.  Or how amazing it is that all the food tastes so good while being generic.

Did you also think Trader Joe’s was a quirky American brand with an amazingly delicious selection of store-brand food?  Would it blow your mind to hear that it’s privately owned by a German family?  Or that the seemingly generic products are outsourced to your favorite Whole Foods brands?  Read that and more here:

The Lingering Effects of Adolescence

I feel like we’re constantly posting all these articles about (not) growing up, but here’s another one from New York Magazine that a friend sent to me.  It’s kind of a long piece, but it could actually be read as a series of mini articles.

>> Why You Never Truly Leave High School <<

I highly recommend reading through the whole thing, so I’ve included some highlights to whet your appetite:

Pg. 1 – The “reminiscence bump” suggests that memories made between the ages of 15 and 25 are the most vividly retained.

Pg. 2 – Your height, weight and attractiveness at the age of 16 are correlated with your adult success and earning power.

Pg. 3 – This part has two interesting proponents.  The first is that when they incited fear in adolescent mice, this fear was vividly recalled in the mice even after reaching adulthood.  The analogous experiment in adults and children did not have the same result; these mice forgot.  Second, high school and other teenage social environments are a fairly modern idea.  Just a couple of generations ago, many teens didn’t graduate from high school and instead worked alongside adults.  Maybe sequestering teens amongst themselves isn’t the most successful idea…

Pg. 5 – In studies where teens were asked who their best friends were, only 37% of them were reciprocated. When asked by high school students to categorize their classmates into groups (Popular, Smart, Jocks, Outcasts…) only 27% and 37% (in two separate iterations of the study) of the thought-to-be-Popular kids thought of themselves as Popular.

Pg. 6 – In 2000, 10th graders were asked to align themselves with a character from The Breakfast Club.  When evaluated 8 years later, these earlier characterizations proved predictive… EXCEPT for the ones who had identified themselves as princesses at 16.  These women – now 24 – had lower self-esteem than the women who had identified themselves as brainy.

Exercise (For) Your Brain!

Breaking news: exercise is good for your brain!  In a study published last April, researchers at Dartmouth tested how a month of exercise can affect a person’s memory.  Not so surprisingly, they found that those that exercised for at least 30 minutes daily showed much improved memory functions than those that had remained sedentary.

Conversely, fatty foods were shown – in a separate study – to seriously detriment the brain’s cognitive functions over time.  In a lab study in rats, they found that a high-fat diet actually lead to an accelerated decline into dementia!  But they also found that exercise effectively counteracted these declines in cognitive function.  So if you think you’re eating too many cheeseburgers, hit the gym, and you should be good!

But both studies found that the positive effects of exercise on the brain (increased neuron production, improved memory, etc) could only be sustained with continued exercise.  In as little as 3 weeks of inactivity, the brain can become indistinguishable from those that had never engaged in exercise to begin with.

This is unrelated but still very interesting:  Babies start to recognize language from inside the womb!!

Daddy Issues

I always thought that the age of the mother was critical.  What I never considered was the possibility that the age of the father is, too!  In the field of epigenetics, studies are finding that the father’s life experiences and hardships have an effect on his sperm and, thus, his offspring.

Some highlights:  Older fathers are more likely to pass on genetic mistakes, resulting in autism and psychological disorders in the next generation; men who grew up in famine are more likely to have offspring with diabetes and weight irregularities.
