Where the Time Goes with Age

By Nathan Yau

We get 24 hours in a day. How do we spend this time? How does our time use change as we get older and priorities shift?

Here is the percentage breakdown in our teens, 20s, and 30s, through to our 80s.

A city is a science experiment. What happens when we separate human beings from the environment in which they evolved? Can people be healthy without nature? The results have beenbleak. Countless studies have shown that people who spend less time in nature die younger and suffer higher rates of mental and physical ailments.

“There’s a really, really strong case for proximity to nature influencing health in a really big way,” said Jared Hanley, the co-founder and CEO of NatureQuant, an Oregon start-up whose mission is to discover what kind of nature best supports human health, map where it is and persuade people to spend more time in it.

Using satellite imagery and data on dozens of factors — including air and noise pollution, park space, open water and tree canopy — NatureQuant has distilled the elements of health-supporting nature into a single variable called NatureScore. Aggregated to the level of Census tracts — roughly the size of a neighborhood — the data provide a high-resolution image of where nature is abundant and where it is lacking across the United States.

When Your Vision and Hearing Decline with Age

By Nathan Yau

If you want to feel like you’re getting old, visit an optometrist and have them tell you that in 6 to 12 months you won’t be able to read things up close and you’ll need bifocals.

For most of my life, I had good vision without glasses or contacts, but in my mid-30s I noticed the basketball score on television looking kind of blurry. I had astigmatism. Just a little.

My prescription didn’t change for years. Until recently. My optometrist hit me with the news that most people start to have trouble reading up close between 39 to 43 years old. I had to look into it.

The following chart shows the percentage of adults who wear glasses or contacts, by age, based on data from the National Health Interview Survey.

Excelentes animações sobre fenómenos físicos como o fluxo de ar em asas de avião ou noutros meios

The dream of soaring in the sky like a bird has captivated the human mind for ages. Although many failed, some eventually succeeded in achieving that goal. These days we take air transportation for granted, but the physics of flight can still be puzzling.

In this article we’ll investigate what makes airplanes fly by looking at the forces generated by the flow of air around the aircraft’s wings. More specifically, we’ll focus on the cross section of those wings to reveal the shape of an airfoil

The jobs of young people with higher incomes and what they studied

By Nathan Yau

Income tends to increase with age, because more work experience and education tends to lead to higher paying jobs. However, young people can also earn higher incomes. Using data from the most recent 2022 American Community Survey, let’s see what those people studied and what they do for a living.

More pets than children in Taiwan

boa estória com gráficos e animações excelentes

In 2018, Taiwan officially became an “aged society,” a label reserved for populations where 15-20% are 65 years or older. But that’s only the beginning. Taiwan’s on track to reach “super-aged society” status around 2025—that’s when the share of folks 65 or older goes over 20%. This rapid demographic shift makes Taiwan one of the fastest aging countries in the world, the social and economic implications of which will need careful planning and strategic policy to address.

Climate Disasters Drain US Emergency Fund, Adding to Government Shutdown Risk

bons gráficos de barras e de linhas acumulados e várias combinações deste tipo de gráficos

By Rachael Dottle and Leslie Kaufman Green + Politics
29 de setembro de 2023

Devastating fires in Maui and the fierce winds and rain of Hurricane Idalia are just two of the record 23 billion-dollar weather disasters the US has experienced so far this year, leaving little left in the primary government relief fund. Diminished resources combined with a potential shutdown of the federal government could hamper the response to any new disasters later this year.

Due in part to a warming climate, major disasters are increasing in frequency and cost, and federal spending on recovery has grown in step. The principal source of direct federal aid is the Disaster Relief Fund. This major source of individual and public aid managed by the Federal Emergency Management Agency is expected to be exhausted by the end of the fiscal year in September.
