So a while back they discovered that when old mice are transfused with blood from young mice it made the older mice younger. This led to the belief that young blood has something in it that makes you young again.

This newest study says that's incorrect. It's old blood that has something in it that makes you age faster. There was never anything in young blood that makes mice/people young. Replacing old blood with new blood just removes the chemicals in old blood that make you age.
My question is should blood letting and leaches be reexamined for medicinal value? If old blood has shit in it that makes you age, and can't be filtered out naturally, then blood letting and leaches should remove it. This was the working theory back in the day before it was abandoned. Why did they abandon it? What specific evidence or proof did they have to doubt blood letting other than too much can kill you?

Couldn't you just make blood donation mandatory for everyone without a blood-transmitted disease?

Obviously blood donation is the modern day version of blood letting and leaches. Having a nurse, that pays you money, to monitor your vitals eliminates that dangerous side effect of taking blood letting too far.

"Old blood" isn't that old, all of the cells have a limited life span and are replaced continually, and fluids are added/removed constantly. Taking blood and then replacing it with blood made internally by an "Old" person isn't going to be that different. A complete exchange transfusion of blood from younger donors may be different (although repeat transfusion is a bad idea for various reasons, including risk of tti that goes up with each donor exposure, development of allo antibodies, iron buildup and required chelation, risk of transfusion reaction or trali, or other transfusion associated organ injury, etc.).
What are these "things in old blood" that have an effect?

Fear the Old Blood

Accumulated substances the body has no mechanism to filter out naturally, apparently.

Would bet money Hillary was getting young girl blood transfusions daily during the campaign.

Leeches are still used. Mainly for the antibacterial properties and for making your blood flow more smoothly.

This is absolute bullshit
Everything in the blood is recycled, with execption given to B memory cells.
Again, aging is because the specialized cells jn the body lose the ability to reproduce, and it isn't exactly possible to replace them when they die.
If blood letting worked the Romans and Arabs would have had life spans longer than 40 years.
Fuck off

lifespan averages were thrown off by exceedingly high child mortality. Fact is if a roman lived to be 20, he had a very good chance to living to 70-80

Now I'm thinking about cutting, not sure if smart choice tho.
