  • you also don’t hear about it as much because people tend to bike more in warm weather so it’s more likely for you to go long stretches of time without biking when it’s getting colder.

    Off topic, but I think it’s funny how cycling is viewed in different parts of the world. You look at it as a hobby that is naturally done less in the winter. For me it’s just a way to get to work and I still have to work when it’s cold, so obviously I’m still cycling just as much. And this is true for a lot of people, the bike rack at my job is almost as full in the winter as it is in the summer.













  • While we’re on the topic of CPR, I want to address the myth that CPR “almost never works”. It’s great at what it does, which is pumping blood through the body enough to keep vital organs supplied with a bare minimum of oxygen so they can survive.

    However, there’s usually a reason why the heart has stopped beating and in most cases, CPR can’t reverse that reason. If the patient is in a car crash and has completely bled out, CPR won’t get any blood back into their system. Or if they’re at the end stage of a terminal disease, CPR can’t magically cure the disease.

    But in cases where the cause for the cardiac arrest is simple and easily reversed, chances of survival are much higher. For example, if someone is drowning and you get them out of the water within a few minutes of cardiac arrest, CPR is very effective, with the majority of patients surviving. Here’s a study with 113 patients who were resuscitated after drowning and only 8 were confirmed dead. For 20 patients, the outcome was unknown, but even if they all died as well, that’s still a 75% survival rate.


  • Yes, a heart that has completely stopped beating cannot be restarted by defibrillation. It only works in a condition called ventricular fibrillation, when the muscle fibers of the heart are still contracting, but are no longer “in sync”. This causes the heart to twitch chaotically, which is not an effective way to pump blood. And without blood pumping, the heart itself does not receive any oxygen as well, so it will eventually go into a complete flatline after a few minutes of untreated ventricular fibrillation.

    The electric shock helps the fibers resynchronize. If you want to see the effect directly, here’s a video:

    Be warned, it shows an open chest and an exposed heart, most likely during heart surgery. They are using spoon-shaped internal defibrillation paddles. In the beginning, you can see the heart in ventricular fibrillation. It’s twitching chaotically and not pumping any blood. After defibrillation, it starts contracting rhythmically again.


  • I’ve never heard of a punctured heart personally, but I do think it’s possible. A punctured lung is much more common. But both conditions are usually treatable if the patient survives.

    CPR does carry some risks, but not doing CPR is guaranteed to be lethal. So any risk (to the patient) is worth taking at that point.



  • Also, Hamas didn’t just come up in a vacuum. People here in Germany are radicalizing because they were asked to wear masks during a pandemic and they heard that brown people are now seeking refuge in Germany. Palestinians have been suppressed, starved and killed for decades and none of the more moderate forces have been able to do anything about it. Not that Hamas would do any better, but it’s understandable that people support more radical movements when they’re literally fighting for their survival.


  • Slaughtering civilians is never justified. What Hamas did was horrifying and a crime against humanity. But the reason why Hamas ever got so strong in the first place has a lot to do with how Isreal has systematically oppressed and killed Palestinians for decades. And the war it is waging now against the Palestinian people is also indefensible. It should be widely condemned, any support withdrawn and Israel should be sanctioned.
