It seems that while the practice of bloodletting throughout history had little or no effect on most diseases, and the practice was abandoned in the 19th century, new research published in BioMed Central's open access journal BMC Medicine demonstrates that blood donation has real benefits for obese people with metabolic syndrome. Two sessions of bloodletting were enough to improve blood pressure and markers of cardiovascular disease.

“Wow...Never thought of blood letting as being in the same vein as blood donation.
Now is that a pun I see??”
Ha, ha, very good!
Well, it makes sense that when you consider how many times in a person’s life in the pre modern age, that they get cuts, wounds, injuries that cause significant blood loss, their ability to survive can depend on how much blood they have left, and its ability to carry oxygen. When you loose blood, the volume gets replaced quickly, but number of RBCs (red blood cells) gets diluted and they take many months to replenish.
Even though loosing a pint or two isn’t dangous, and even if you had a week or so to recover, if as a poor substance farmer or warrior you had several serious blood loss injuries in a row in one unlucky month or summer, even though none of the events should have been serious enough to be deadly, you might not survive the 4th one because your blood is so thin by that point.
The number of people that have survived thanks to blood that is really on the thick side they had more RBCs before the first injury so they still have more after the last and may survive. This kind of trait that gets selected.
I considered donating blood regularly to see if it would reduce my cholesterol without statin drugs but I never did it. It seemed to simple a solution. Now it seems I had a good idea and should have gone ahead.

Ha, ha, love the picture! I think they used the term bloodletting just to get one’s attention. What they are getting at is that donating blood may very well benefit donors as well as recipients.
I have no doubt that anyone other than the young and “perfect” will be denied care under Obama’s socialized system. The Nazis would have approved.
