ADHD is not a form of autism, while they're often co-morbid, they have separate and non-overlapping diagnostic criteria.

They are both forms of "neurodivergence," but not the same.

My SO was just talking about this sort of system the other day. It's being test piloted at a few different manufacturing facilities for removal of different kinds of chemicals. They work for an environmental contracting company and they just got the greenlight to set one up. From what I hear it's pretty neat and stands to be the next big thing in wastewater treatment.

Road Traffic Noise and Incidence of Primary Hypertension: A Prospective Analysis in UK Biobank

Abstract:

>Road traffic noise was estimated at baseline residential address using the common noise assessment method model. Incident hypertension was ascertained through linkage with medical records. Cox proportional hazard models were used to estimate hazard ratios (HRs) for association in an analytical sample size of over 240,000 participants free of hypertension at baseline, adjusting for covariates determined via directed acyclic graph.

>During a median of 8.1 years follow-up, 21,140 incident primary hypertension (International Classification of Diseases 10th Revision [ICD 10]: I10) were ascertained. The HR for a 10 dB[A] increment in mean weighted average 24-hour road traffic noise level (Lden) exposure was 1.07 (95% confidence interval: 1.02, 1.13). A dose-response relationship was found, with HR of 1.13 (95% confidence interval: 1.03, 1.25) for Lden >65 dB[A] vs ≤55 dB[A] (P for trend < 0.05). The associations were all robust to adjustment for fine particles (PM2.5) and nitrogen dioxide (NO2). Furthermore, high exposure to both road traffic noise and air pollution was associated with the highest hypertension risk.

>Previous studies have shown a connection between noisy road traffic and increased risk of hypertension. However, strong evidence was lacking, and it was unclear whether noise or air pollution played a bigger role. The new research shows that it is exposure to road traffic noise itself that can elevate hypertension risk.

>The findings can support public health measures because they confirm that exposure to road traffic noise is harmful to our blood pressure, she said. Policymaking may alleviate the adverse impacts of road traffic noise as a societal effort, such as setting stricter noise guideline and enforcement, improving road conditions and urban design, and investing advanced technology on quieter vehicles.

These are some important findings, especially given how the majority of humanity now lives in urban environments. Policymakers should take heed and look to reduce the noise in cities not just through quieter vehicles but by reducing the number of vehicles overall. Anecdotally, during the early days of the pandemic, many of us have experienced how quiet cities could be with reduced traffic volumes.

Nope. While you are right that there is a thing called deepwell disposal, it happens in other parts of the oil and gas industry. The byproduct of the oil sands isn't disposed of in deepwell disposals. At least when it comes to the surface mines.

When it comes to them having to extract the oil from the ground, yes, deepwell disposal is done. Because the well is already there for them to use.

Word. I used to deal with a lot of resentment towards my (loving, supportive) family because I thought they didn’t understand my needs, that they didn’t understand me.

After a lot lot lot of work with a fantastic therapist, I came eventually to realize that the problem was my struggles with communicating my needs. I was resentful because I had this expectation that they should just know what I wanted from them, but I never spoke up for myself or communicated openly or receptively.

So I started practicing that honest communication. I started practicing hearing people’s feedback, listening to it, and accepting it I practiced reminding myself that people can’t read minds- if I want my family to understand something that’s happening within me, it’s my responsibility to be vulnerable and share it.

Now, after years of practice and hard work, I don’t feel resentment or frustration toward my family about… anything. I feel forgiving and I feel capable of being myself around them, and I feel secure in the knowledge that if I tell my family I need something, they can hear it. They can’t always provide it but they care enough about me to at least be supportive.

I’m very fortunate in that regard, I’ll admit, but it was still a very difficult thing for me to realize and recognize.

Resentment and forgiveness can’t be flipped on and off like a switch. They’re muscles that need regular exercise. It’ll be hard at first but every day it gets a little easier.

Edit: another thing that helped me a lot was getting sober. I had some substance abuse issues that got in the way of a lot of this growth but with sobriety I was able to finally grow toward becoming the man I want to be.

To do something we'd either need to be in a position of extreme influence, or be disgustingly rich. Even if they were to be a politician they'd have to content with the rest of the political forces being paid off by lobby groups.
