Stay in school!

NY Times:
"The evidence is overwhelming that college is a better investment for most graduates than in the past. A new study even shows that a bachelor’s degree pays off for jobs that don’t require one: secretaries, plumbers and cashiers. And, beyond money, education seems to make people happier and healthier. ....
The most unfortunate part of the case against college is that it encourages children, parents and schools to aim low. For those families on the fence — often deciding whether a student will be the first to attend — the skepticism becomes one more reason to stop at high school. Only about 33 percent of young adults get a four-year degree today, while another 10 percent receive a two-year degree."

City Life Could Change Your Brain for the Worse | Wired Science | Wired.com:
"Meyer-Lindenberg’s findings, published June 23 in Nature, are a neurological investigation into the underpinnings of a disturbing social trend: As a rule, city life seems to generate mental illness.

Compared to their rural counterparts, city dwellers have higher levels of anxiety and mood disorders. The schizophrenia risk of people raised in cities is almost double. Literature on the effect is so thorough that researchers say it’s not just correlation, as might be expected if anxious people preferred to live in cities. Neither is it a result of heredity. It’s a cause-and-effect relationship between environment and mind."

That last sentence is a brave one.

The Sun Is the Best Optometrist - NYTimes.com:
"...the rapid increase in nearsightedness appears to be due to a characteristic of modern life: more and more time spent indoors under artificial lights.

Our genes were originally selected to succeed in a very different world from the one we live in today. Humans’ brains and eyes originated long ago, when we spent most of our waking hours in the sun. The process of development takes advantage of such reliable features of the environment, which then may become necessary for normal growth.

Researchers suspect that bright outdoor light helps children’s developing eyes maintain the correct distance between the lens and the retina — which keeps vision in focus. Dim indoor lighting doesn’t seem to provide the same kind of feedback. As a result, when children spend too many hours inside, their eyes fail to grow correctly and the distance between the lens and retina becomes too long, causing far-away objects to look blurry"
