Honestly, the whole concept of autonomous AI driven companion robots seem like that xD

Reply to comment by Ardet_Nec_Consumitur in Researchers have found the genetic links between headaches, migraines and blood sugar levels, which ultimately could lead to targeted treatments for patients by giuliomagnifico

Caffeine actually makes your blood vessels constrict, not relax. From what I know, migraines are an abnormal response to the blood vessels in your head relaxing, and normal headaches can be caused by dehydration too. Caffeine helps because it raises your blood pressure by making your blood vessels constrict. That's why some headache medications have caffeine in them. Drinking enough water also helps because it raises your blood pressure. I noticed my migraines became less frequent when I started drinking coffee regularly and making sure I drink enough water, along with avoiding other triggers.

If your migraines are neck pain related, then the relaxation/masaage can help too.

Reply to For marginal occupations licensed by U.S. states, the welfare costs of licensing exceeds the benefits, as workers have to expend resources to obtain the license and consumers pay higher prices.

Cool study. Does suggest that using a signal to impute quality for consumers can have sizable losses, for those who wouldn’t get a license but would work, and for consumers.

The distributional impact is also important, as higher prices may preclude lower income Americans from performing needed repairs.

Note that this welfare loss does not take into account quality measures of work performed, which would mitigate the losses.

The point is that licensing imputing quality signals can and does have a net welfare loss before you take into account changes in quality.

Are you going to drive me? Because as someone with epilepsy, it's very hard to get to one of those "better jobs". And are you going to help me get accepted? Because so far no matter what I've tried, I haven't been able to get accepted into any, even with my diploma and some college-level education.

As if regular cars are affordable currently anyway.

They are starting to bring electric car incentives in in Australia. For instance you can lease an electric car now through salary sacrifice and not pay fringe benefit tax, effectively reducing your tax by a third of the cost of the car which is pretty good.

Oh I’ve never heard or made the connection that relaxation after stress can trigger a migraine. How interesting. Mine definitely can be triggered by stress but haven’t noticed the stress/relaxed connection for myself.

I have multiple causes too, back/neck, strong scents, bright lights, wine, stress too much information to absorb around me (information overload), hair tied back, oversleeping and intense dreams.

Findings in title quoted from the linked release^1 and peer-reviewed research article:^2

From the linked release:^1

>The study, published February 24 in JAMA Network Open, is one of the largest to date to look at the effects of long-term exposure to fine particle air pollution, which is emitted from sources such as vehicles, smokestacks, and fires.

>Fine particle air pollution, also known as PM2.5, are fine particles that are 2.5 micrometers in diameter or smaller.

>The researchers tied each adult’s address to a specific geographical location — a process known as geocoding — to establish annual average exposure to fine particle pollution so it could be linked to annual PM2.5 exposure data.

>Then they identified the patients diagnosed with a heart attack or who had died from heart disease or cardiovascular disease.

>The research lends support to current efforts to make the country’s air pollution standards more stringent.

>In January 2023, the EPA [Environmental Protection Agency] announced a proposal to tighten the annual PM2.5 standard by reducing the acceptable level to between 9.0 to 10.0 micrograms per cubic meter.

>The EPA said it was advising this change because the current standard did not adequately protect public health under the guidelines required by the Clean Air Act.

From the peer-reviewed research article:^2

>Findings In a diverse cohort of 3.7 million adults, this cohort study found that long-term PM2.5 exposure was associated with an increased risk of incident acute myocardial infarction, ischemic heart disease mortality, and cardiovascular disease mortality, and these associations were more pronounced in low socioeconomic status communities.

>This study also found evidence of associations at moderate concentrations of PM2.5 below the current regulatory standard of 12 μg/m3.

>Meaning This study’s results add to the growing evidence that long-term PM2.5 exposure is associated with increased risk of cardiovascular events and that the current regulatory standard of 12 μg/m3 is not sufficiently protective.

Bring on electric cars. I'm so sick of the poor city air quality, and the noise. Electric cars would be the biggest improvement we can make as a society honestly.
