Summary

A new Lancet study reveals nearly three-quarters of U.S. adults are overweight or obese, a sharp rise from just over half in 1990.

Obesity among adults doubled to over 40%, while rates among girls and women aged 15–24 nearly tripled to 29%.

The study highlights significant health risks, including diabetes, heart disease, and shortened life expectancy, alongside projected medical costs of up to $9.1 trillion over the next decade.

Experts stress obesity’s complex causes—genetic, environmental, and social—and call for structural reforms like food subsidies, taxes on sugary drinks, and expanded treatment access.

Yes, but there is also little enforcement on extremely loud exhausts and excessive engine revving. People should not be subject to noises loud enough to require hearing protection on a regular basis. Some studies are also finding that car noises in general generate stress responses in humans and long term exposure inreases the chance of some health conditions.

You could also argue road speed and road design should factor in to a noise reduction plan at a city planning level. Cities could enforce lower speeds in certain areas to reduce noise. If the city insists on funneling cars in a certain area they could also be responsible to install sound barriers, maybe even a thin tree line to help buffer noise near residential or certain commerical areas.

Absolutely, though as someone who notices louder exhausts I gotta say that, as much as they stand out, they’re really quite rare. It’s the never-ending drone of tires on pavement, loud cooling fans, heavy diesel trucks, and whatever other clattering and clanging that make up the bulk of the noise. The main street where I live goes pedestrian in the summer and I remember just how much noise a late-ish model Honda Civic made as it drove across it slowly one day even though it’s engine was essentially silent. The contrast between the peaceful pedestrian street and this single, “very quiet” sedan was startling. I already had sorta known but that moment is really where I decided that there’s no such as thing as a “quiet” car.

Our school busses have gone electric, though, and city busses are rapidly being replaced with hybrids that are quiet when they sit or need to accelerate. Those have reduced a lot of noise, and that’s super nice, but again they’re not the bulk of the noise. Removing the worst offenders but keeping the “quiet” cars doesn’t actually help beyond making us feel like we did something. We gotta start making main, commercial streets pedestrian only year-round. We gotta start being aggressive about making public transit accessible. We gotta start building on a human scale.
