If you're wondering what's like being Venezuelan. We just had a death in the family and we hosted an online wake because the 26 of us are in different countries and we couldn't be together any other way.

It's been two days, and all I can say about Venezuela is that this whole "the end justify the means" and "the enemy of my enemy is my friend" couldn't be further away from the truth. They might have kidnapped/taken Maduro but they left the dictatorship in place.

Americans & Europeans needlessly exposing African babies to preventable diseases just to see if they can find something that would justify their preexisting antivaccine beliefs is not only unscientific and actually anti-science, it is very much reminiscent of colonialist, racist human rights abuses
“It is not clear what the research question is. It seems to be about the safety of the vaccine rather than its effectiveness, but both are already well-established, and to undertake such a study in a population where almost 1/5 of the adult population has a marker of infection seems extremely risky”

Just need to be clear that the US Air Force almost caused a major commercial flight catastrophe because they are flying over Venezuela with transponders off
NOT GOOD 🫠
‘the air traffic controller noted not seeing the military aircraft on their end, as it had the transponder off and was not transmitting its location.
“We almost had a midair collision up here,” the pilot said, according to ATC recordings. "They passed directly in our flight path ..."’

10 yrs ago today I stopped drinking - forever. It took ~2 of those yrs to say "I don't drink" instead of making excuses to explain my abstinence.
Dunno if anyone needs to hear this, but if you feel need to stop but can't...you can! And when you do, no-one needs an explanation. 🙂 #chemsky
