I found this video very informative. I've often wondered why so many people seem to behave irrationally. I suspected that fear is a major motivator, and this video supports that idea.
By nature, I'm a cautious person. I've seen many friends, family members, coworkers, and others pass away prematurely. The world is a dangerous place.
During the 2024-25 season, only 23% of adults aged 18 and older received the updated COVID-19 vaccine as of the week ending April 26, according to CDC data.
Among children, just 13% of them received the updated COVID vaccine over the same period, the data shows.
Dr. Gregory Poland, a vaccinologist and president and co-director of the Atria Research Institute -- which focuses on disease prevention -- said there are likely not enough people receiving the vaccine, which is contributing to the number of weekly COVID deaths.
Additionally, Poland said that immunity from COVID-19 vaccines wanes over time, increasing the likelihood of being infected.
This is why the current recommendation for those aged 65 and older is to receive two doses of the updated COVID vaccine six months apart.
The gains were modest but meaningful. One patient improved by two stages on the Hoehn–Yahr scale, a widely used measure of Parkinson's severity. Another saw a 50% improvement in motor function during off-medication testing.
"It is a significant achievement that we have been able to confirm improvement in patients' symptoms," said Jun Takahashi, director of Kyoto University's Center for iPS Cell Research and Application, who is leading the research. "We hope to deliver this treatment to patients as soon as possible."
Correlation is not causality. It could be that healthier people are more likely to engage in brief vigorous activities.
Nevertheless, short vigorous exercise is likely to be beneficial. I prefer to ride my bicycle for 25 minutes.
I found the chart confusing because the bottom histogram is the number of people who met the criteria. The top of the graph shows a curved relationship between exercise and health.
My doctor told me that if I take pain medication for actual pain, I should be fine, but if I take it for fun, then I would be in trouble. I took pain medication after surgery, but got off it as quickly as possible.
This is an old video. Kurzgesagt eventually took it down because the accuracy was criticized, but I think that it is interesting:
