Reply to comment by BardTheBoatman in Research found among nearly 100 teens who underwent brain scans, those with obstructive sleep apnea (OSA) tended to have thinner tissue at the brain's surface, and some signs of inflammation in a brain area key to memory and learning. by Wagamaga

I've had OSA since probably 13. I'm 33. I just had a surgery to correct my deviated septum, and that plus a dental sleep appliance ensures that I can breathe at night, but I still feel I have a much lower "energy limit" than I otherwise should have (i.e. even good sleep only recharges my batteries to 80% at best.)

I wonder if that's the result of permanent brain damage from 20 years of sleep apnea

I don’t rate the Apple Watch oxygen monitoring. It only samples about 10 times in a single nightly sleep period. I sometimes wear an oxygen monitor and it never correlates with the watch. I’m on CPAP too.

Reply to Aggregate measure of financial misreporting for nearly 2,000 companies in the U.S. suggests that the collective probability of fraud across major companies is the highest in over 40 years by marketrent

Excerpt from the linked summary^1 about an aggregate measure of financial misreporting:^2

>False information on balance sheets has “real economic effects because it represents misinformation on which firms base their investment, hiring, and production decisions,” Dr. Beneish and his co-authors—David Farber of Indiana University-Purdue University in Indianapolis and Matthew Glendening and Kenneth Shaw, both of the University of Missouri—wrote in December.

>Messod D. Beneish, a professor of accounting at Indiana University who developed the M-Score in the 1990s, and several co-authors have calculated an aggregate score for nearly 2,000 companies.

>The M-Score is calculated from eight ratios on a company’s balance sheet, all numbers that public companies report quarterly, and comparing the ratios to earnings statements from a year earlier.

>The “M” is for manipulation, and uses a company’s financial statements to determine whether it is engaging in manipulation.

>“We think this is a measure of misinformation in the economy,” said Dr. Beneish. The new aggregate measure was published in a December paper, and the latest data—compiled in March and shared with The Wall Street Journal—shows that the collective probability of fraud across major companies is the highest in over 40 years.

> 

>There are ways for companies to manipulate all these metrics to appear profitable even when actual sales aren’t improving.

>For example, one of the eight metrics raises a flag if a company abruptly starts reporting more “receivables,” that is, more money owed to the firm but not yet paid.

>Another flag goes up if a company reports higher values of assets that cannot be sold, and that aren’t clearly identified as plants, property or equipment.

>A third metric looks at changes in accruals, which is when an expense has been incurred, but not yet paid. Another identifies whether companies change how much depreciation they take.

>Dr. Lee, now a professor at the University of Washington in Seattle, says that any of the eight metrics wouldn’t necessarily mean trouble.

>But when the score of the combined metrics is rising, it shows “a growth company, with core businesses that are eroding, that is running out of economic steam and using aggressive accounting,” he said. Even if the accounting is legitimate, he added, “you may want to avoid that company.”

Weight gain/health changes/age all can play a part. Also if you still have your tonsils and adenoids those can cause an obstruction in your air passageways. See a doctor and get a referral for bother sleep study to at least rule sleep apnea out. Or if it is sleep apnea they can discuss a treatment plan with you.

Sleep tech here - get a sleep study done! Your watch is not a doctor, but for sure providing you with info you could and should discuss with one.

Reply to Road Noise Makes Your Blood Pressure Rise – Literally | Study shows the sound of traffic is associated with increased risk of hypertension, calls for public health measures to reduce noise exposure by Hrmbee

Tires can be a major factor in road noise. For commercial vehicles, some tires are way noisier than others, and also can affect fuel (energy) consumption. I dream about the day when I go to work and a true hybrid truck is waiting for me. No more diesel deafening noise for me or neighbors. Noise pollution will drastically decrease as soon as fuel cell or electric commercial vehicles are massively adopted.

Sadly, this is one of those things that varies hugely from person to person. I lucked out and found one I like on the second try, one of my friends took 4 tries to find one for her.

Reply to comment by needtofigureshitout in Study Suggests Wild Blueberries Help Burn Fat. Results showed participants burned notably more fat after consuming wild blueberries. For example, fat oxidation rate rose by 19.7%, 43.2%, and 31.1% at 20, 30, and 40 min after cycling. by Wagamaga

>Why would i be involved in the study?

...most people don't have a newly-created throaway almost entirely devoted to one post. It's fascinating, you are all throughout only these comments on a newly created account

It's interesting, so I'm trying to work out as to why -- and you won't actually say no. For the third time, were you involved with the study in any way, or know the authors?

>Because I'm calling out the fact that you omitted information that would render your initial comment entirely pointless had you included it?

I don't believe you did, there being a washout isn't really relevant for my points and something is lost in translation.
