  3. finally someone on YouTube that can actually can explain this…

  4. I am AB/Neg other problems they say. People with an extremely rare blood
    type could be at a higher risk for developing memory problems later in
    life. A new study published in the journal Neurology says people with AB
    blood type could be up to 82 percent more likely to develop problems with
    cognition and memory as they age.

    Researchers examined data from a study of over 30,000 people aged 45 and
    up. They identified a cohort of 495 people who developed memory or
    cognitive impairment over approximately three-and-a-half years. The
    participants were given four cognitive tests over the course of the study.
    They were compared to a similar group of 587 adults who did not have any
    signs of memory problems.

    While only 4 percent of the U.S. population has AB blood, 6 percent of the
    cohort with memory problems had this blood type. Researchers concluded that
    in this study people with AB blood type were 82 percent more likely to
    develop thinking and memory problems than people with any of the three
    other blood types.

    Interestingly enough, the researchers also discovered that people with
    higher levels of factor VIII, a protein which helps clot blood, were almost
    a quarter more likely to have cognitive problems than those with lower
    levels. People with blood type AB were generally found to have higher
    levels of the protein than others.

    “Our study looks at blood type and risk of cognitive impairment, but
    several studies have shown that factors such as high blood pressure, high
    cholesterol and diabetes increase the risk of cognitive impairment and
    dementia,” study author Mary Cushman of the University of Vermont said in a
    release. “Blood type is also related to other vascular conditions like
    stroke, so the findings highlight the connections between vascular issues
    and brain health. More research is needed to confirm these results.”

    As Cushman mentioned, other studies have looked at the link between blood
    types and increased likelihood of certain diseases. A 2012 study conducted
    by Harvard University researchers concluded that AB blood types have a 23
    percent higher chance of developing coronary heart disease compared to O
    blood types. And in line with researchers finding that AB blood types have
    higher levels of factor VIII, a study from 2013 found because of this,
    those people are at a higher risk for developing dangerous blood clots.

    So what if you have AB blood type? Don’t panic, experts say. Head of
    Alzheimer’s Research UK, Simon Ridley said the study did not look at the
    direct link between blood type and dementia. “Current evidence suggests the
    best ways to keep the brain healthy are a balanced diet, not smoking and
    regular exercise,” Ridley told the BBC

  5. Totally helped me understand this entire content. Thanks so much.

  6. The first time I donated Blood they sent me a letter and told me I was a
    rare blood donor and that I had O blood. The letter said it was the only
    blood type in the beginning. I don’t know if it is positive or negative but
    i asked one of the ladies on the Blood Mobile what it meant the next time
    they came to Beaverdam and she said it was not my blood type that made it
    rare but that it was the antigens that made up my blood that made it rare.
    I still do not understand what they mean. I was wondering Did any one else
    who donates blood get a letter like this and do they just say that to try
    to get more blood? I think I am a Universal donor but I can only receive my
    blood but I am not positive. I don’t have a clear understanding of

  7. Great explanation! 

  8. relief. I get it now. Thanks. :)

  9. i m an O+

  10. I’m A+.

  11. im a C .. what does that mean.

  12. You didn’t mention plasma. AB is the universal donor… $$$$ in my case!

  13. I am AB+ so that means give me your blood punks but stay away from mine. I
    am a greedy bastard, love it. I think AB+ is Awesome.

  14. Correction I can only receive my blood type.

  15. “….Make some money”… man where the fck am i?

  16. I’m B+

  17. Great teacher!

  18. AB would be lazy people people who just take from society and never
    contributing back, O type people would be the hard workers always giving
    and never asking anything in return lol =) 

  19. Where are the sample problems?

  20. Thank you very much! I appreciate the help from this video a lot! 

  21. I’m A+

  22. I wonder how they find the blood type out? Do they put it on the blood

  23. He is pretty much focusing on ”You will probably die”
