Most people can, but some people have fructose intolerance/malabsorption or even sucrose intolerance (similar to lactose intolerance where they can't make enough of an enzyme).
After it's absorbed, fructose goes straight to the liver, and unlike glucose (which in excess is stored as glycogen), the liver doesn't really know what to do with excess fructose, so a good chunk of it is stored as liver fat.

It's never a bad thing to remind those amongst us that know, but still live an unhealthy lifestyle. I'm sure I'm one of those people or I wouldn't have scrolled the comments.

This sounds as though it is a mechanism existing within all of us, meaning there should be high correlation between excessive fructose consumption and Alzheimers. I don't know if there is. Did they find something in people with Alzheimers like hyperactivity of the fructose foraging response? A higher level of a protein involved in it? Mind you I did not actually read the article

Reply to comment by dbx999 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
Why the other person snipped that line out is beyond me. Here is the whole paragraph and it is very clear that when you adjust for healthy living, the benefits of being vaccinated are even more obvious:
"Thus, the vaccinated would likely face lower COVID-19 risk even if not vaccinated. After controlling for these selection effects, we found substantial vaccine protection against death, but also increasing two-dose RMR over time, and large differences in RMR after two doses between younger (age 18–59) and older (age 60+) people. These findings imply that boosters are highly important in reducing mortality, especially for ages 60+."

Incidentally, many participants had trouble completing the daily assessment, because they experienced cognitive failures such as leaving sections unfinished due to distraction, failing to remember what they did that day, or unintentionally allowing their mind to wander.

The research behind birth rate decline accounts for socioeconomic factors ie it doesn’t matter if economy is great and everyone is earning well. The birth rate will still decline due to something that happened with industrialization. The only countries that aren’t seeing this yet are in central Africa.

Yeah, I discovered the real thing after moving out on my own and haven’t touched the fake crud in decades. Breakfast as a kid was usually a sugar loaded breakfast cereal that turned the milk weird colours.

Reply to comment by WanderingPickles in Cultivating a sense of perspective about pet loss can lead to post-traumatic growth after their death by chrisdh79
I have always liked animals better than people, and get tremendously attached in fairly short order to an animal. For me, I think part of it is because I have determined that I will never have children, but a pet still gives me a little soul to love, a little life that depends on me to give my own life some structure and responsibility. A little creature who will love me with the unconditional love of a child, but for their whole lives. They listen when I talk to them, don’t talk back or yell, have ulterior motives or hidden agendas, they don’t lie to me or take advantage of me. I don’t have to worry about them judging me, so I am free to be my authentic self.
And it’s nice to have a little fluffy animal to cuddle when I’m sad.

>Weird, my Dad always used corn syrup on his waffles and pancakes.
I grew up thinking "Mrs. Butterworth's" was maple syrup. I think most people are probably actually just using flavored corn syrup without knowing it.
Also grew up thinking margarine was "butter."

For me, it was about learning to focus on all the happy memories I had with my cat, and not the stress and the fear and despair I felt at the end of his life. I choose to remember how he would wait at the door for me when I got home, or slept with me every night with his little paw in my hand (if I rolled over, he would climb over my head to the side I was facing so he could put his paw in my hand). Even how well he did taking his inhaler and how much life it gave him that he started playing again at 16. My funny pictures of him in a little sweater, or a bow tie. How he fussed until we gave him a chair of his own in the computer room so he could sit next to me, or lay on my desk as I was on the computer. How he seemed to know when I was sad and came to cuddle with me. How he was obsessed with boxes, so we had several around the house for him to sit in. Or even how he hid the remote for our sound bar and we didn’t find it until after he passed away, he never chewed on the buttons or anything, just put it in one of his boxes.
I choose to remember those good and happy times, and that I gave him the best care I could for the time I had him.

Except they're wrong.

>The IPCC infamously fails to account for carbon cycle feedbacks and their associated tipping points when setting their own emissions targets.
Then why are climate models used in previous IPCC reports so accurate and have predicted the pace of warming so well? Observed warming tends to track middle-of-the-range estimates from previous IPCC reports.

You probably should listen to what actual climate scientists say on the matter-

There were some models for the recent ipcc report that overestimate future warming and they were included too
https://www.nature.com/articles/d41586-022-01192-2
There is no evidence for projected warming <3-4C of any tipping points that significantly change the warming trajectory. Read ipcc report and read what climate scientists say instead of speculating:

"Some people will look at this and go, ‘well, if we’re going to hit tipping points at 1.5°C, then it’s game over’. But we’re saying they would lock in some really unpleasant impacts for a very long time, but they don’t cause runaway global warming."- Quote from Dr. David Armstrong Mckay, the author of one of recent studies on the subject to Newscientist mag. here are explainers he's written before-
https://climatetippingpoints.info/2019/04/01/climate-tipping-points-fact-check-series-introduction/ (introduction is a bit outdated and there are some estimates that were ruled out in past year's ipcc report afaik but articles themselves are more up to date)

David Spratt and Ian Dunlop- authors of this "report" are the same people who have written the report which was panned by scientists who fact-checked it- https://climatefeedback.org/evaluation/iflscience-story-on-speculative-report-provides-little-scientific-context-james-felton/
