Reply to New review finds that rocket emissions in the upper atmosphere can affect the ozone layer but are not regulated — Global annual launches grew from 90 to 190 in the past 5 years, and an upsurge in rocket launches may potentially undo decades of work to save the ozone layer by marketrent
Sounds like someone needs construct a Space Elevator.

Unrelated, but when I first read "vet" I interpreted it as "veterinarian" and was like "why would an animal doctor be deployed to saudi arabia" for a good minute before I figured out what I misunderstood

Each launch is roughly the equivalent of a 747's worth of fuel (kerosene or methane).

I was a submariner. I started taking vitamin D after a psychologist gave my division a speech about her experiences with treating veterans who had alarmingly low vitamin D levels. The next time I went underway, I brought a bottle of 5000iu supplements with me, and it was a night and day difference. I started to feel like normal and part of a team, and not like I was in prison. I work nights and still take them sometimes, especially if I start to feel signs of seasonal depression or general depression symptoms.

I agree he probably painted the effects of coal smoke. I think the clearest example would be in the painting series of London, Houses of Parliament. Several of them having "effect of fog" or "in the fog" in the title so that's what he was aiming for.
But the effects of his vision change can be seen in the water lilies especially around 1918.

Yes, depression is a side effect of vitamin d deficiency. It’s an important one to not overlook.

It's pretty well established that one of the symptoms of vitamin d deficiency is depression.

I'm a vet in Wisconsin. Had a real bad time last year around January when I got back from a deployment to Saudi Arabia. Vitamin D supplements, running intervals, and eating an overly healthy diet fixed it after a while. Not sure if it was sunlight or heat, but it just felt like I had dread going on in the morning and the evening. Thermostat set to 70-72 range, and I would still shiver. Seems to have fixed itself since then. Would be curious to know if it was a fluke or if the/my human body is not good at adjusting to such jarring changes in daily sunlight.

This study seems to point towards the “dreamy haze” being a progressive symptom of his cataracts, however much coal smoke was across Europe at this time.

As you have shown the percentages can you also give us a link to the mass of the fuel reflected in these percentages. I think that would help in quantifying the amount of admission being dumped into the different layers of our atmosphere.

Reply to comment by [deleted] in An anti-aging gene discovered in a population of centenarians less prone to cardiovascular complications, has been shown to rewind the heart's biological age by 10 year by giuliomagnifico
My husband's side of the family has pretty bad cancer history. His grandfather died of Lung Cancer at 75, one uncle died of sudden stomach pain (after suffering most symptoms of stomach cancer ) and the other uncle died of liver cancer. Neither uncles made it to 60. Both had bad addictions towards alcohol and tobacco. Not sure if it's the gebes or their lifestyles. My husband doesn't regulate his eating habit, eats out at every chance, preffers sugar, refined flour etc over whole grains. We are both I our early 30s (I just turned 30 and he is 32) but I get sleepless nights thinking what if my husband gets it. I would need this gene for him!

Have you read the journal articles you’ve cited? They provide compilations of data and make some statistical inferences, i.e. correlation. They do not, nor do they purport to, establish a causal link between latitude and suicide rates.

We already know this. Vitamin D both bolsters your immune system and reduces depression. That's why many scientists pushed back on Covid guidelines and restrictions urging and sometimes forcing everyone to remain indoors.

Is it believable? Do you believe it? To me it feels like the latest, the greatest, the newest, and the soundbitiest nonsense du jour'.

> The Bristol team, led by Professor Paolo Madeddu, has found that a single administration of the mutant anti-aging gene halted the decay of heart function in middle-age mice. Even more remarkably, when given to elderly mice, whose hearts exhibit the same alterations observed in elderly patients, the gene rewound the heart’s biological clock age by the human equivalent of more than ten years.
That's where "rewind" comes from. It restored cardiac function in elderly mice when administered late in life.

I’m 34. I lift. Have lifted since I joined the military. Stopped and started several times over for months to years. You just kinda do it, cause it’s what you’re use to. I Can definitely see myself lifting 20 years from now. I mean.. I’ve already done it for 17.

Insert looks of surprise and shock here.

Life long Seasonal Affective Disorder has been much better this winter due to vitamin D recommendation! Taking 2000 IU a day since October and have had much less depression! Possibly saved my life.
