Coffee

Is it ruining your productivity?

In other words, that euphoric short-term state that you enter after drinking coffee is what non-habitual caffeine consumers are experiencing all of the time. The difference is that for coffee drinkers, the feeling doesn’t last. “Coming off caffeine reduces your cognitive performance and has a negative impact on your mood. The only way to get back to normal is to drink caffeine, and when you do drink it, you feel like it’s taking you to new heights,” Bradberry explained. “In reality, the caffeine is just taking your performance back to normal for a short period.”

See, for me, the thing is that I can’t even tell whether or not I’ve had any. I just drink it for medicinal purposes. In fact, even though I now drink two cups almost every morning, I don’t consider myself a “habitual” drinker, because that implies that it’s a habit. It really isn’t, for me. I sometimes forget to drink it.

This seems like a big breakthrough, not just for people without spleens, but for iatrogenic disease in hospitals:

To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen. Five hours after infection, 89% of the rats whose blood had been filtered were still alive, compared with only 14% of those that were infected but not treated. The researchers found that the device had removed more than 90% of the bacteria from the rats’ blood. The rats whose blood had been filtered also had less inflammation in their lungs and other organs, suggesting they would be less prone to sepsis.

The researchers then tested whether the biospleen could handle the volume of blood in an average adult human — about 5 litres. They ran human blood containing a mixture of bacteria and fungi through the biospleen at a rate of 1 litre per hour, and found that the device removed most of the pathogens within five hours.

That degree of efficacy is probably enough to control an infection, Ingber says. Once the biospleen has removed most pathogens from the blood, antibiotics and the immune system can fight off remaining traces of infection — such as pathogens lodged in the organs, he says.To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen.

Note that it could also be effective against ebola.
