Reply to comment by keylimedragon in High coffee consumption may triple kidney disease risk in some people by LordNPython

>The report says they're treating a cup as 100mg of caffeine from Italian espresso.

Traditionally that would also be made with coffee containing more robusta beans in Italy, which has higher caffeine than the Arabica coffee generally used in the US. A double shot of espresso made from arabica in most coffee shops would likely contain 60mg to 80mg of caffeine.

"Espresso typically has 63 mg of caffeine in 1 ounce (the amount in one shot), according to Department of Agriculture nutrition data. Regular coffee, by contrast, has 12 to 16 mg of caffeine in every ounce, on average. That means that ounce for ounce, espresso has more caffeine.6/01/2023"

Reply to comment by sw33tr3l33s in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

In this particular case, the sentence mentioned above is clearer when not taken by itself. In the paper, it is immediately preceded by "We found substantially lower non-COVID natural mortality risk for vaccinated than for unvaccinated persons." That statement clarifies why they suggest that because vaccinated individuals die less from all causes, they likely would die less from COVID too, regardless of the effectiveness of the vaccine itself.

Reply to comment by runawaycluetrain in The brain can rapidly detect and process fearful faces that are otherwise invisible to the eye. There appears to be a neural pathway for detection of fear, which operates automatically, outside of conscious awareness. by Wagamaga

Thanks for being extra stupid while trying to sound smart but that isn't true.

X-rays/gamma rays/radio waves are not invisible to humans and they are part of the electromagnetic spectrum.

384 going up to 784. Pandemic certainly was the cause of the drop during Trump. The key point is that Biden is enthusiastic about drilling, with equal fervor as any Republican President.

His poll numbers will melt if he came out and said he wanted to double gas prices to fight climate change.

That's the way all animals are, shortsighted and selfish. People who are climate aware consume just as much as the ignorant.

If we have the ability and choice to consume, produce and reproduce at unsustainable levels we will. That ability and choice needs to be taken away.

Just a reminder that keeping things under 1.8C is nowhere near possible without a global shift to a plant-based diet.
