Well - that data is really almost nothing useful - and usefullnes of those idiocy about blood is too quite limited.

And those "research" it is almost NOTHING about behaviour at all !

Only important issue making potentially a difference is "mental health". But what the fuck they meant by that ? God only knows...

And taking other examples: http://article.sapub.org/10.5923.j.ijpbs.20201002.02.html https://iranarze.ir/wp-content/uploads/2016/10/5567-English.pdf https://www.textroad.com/pdf/JAEBS/J.%20Appl.%20Environ.%20Biol.%20Sci.,%205(8)45-49,%202015.pdf https://www.sciencedirect.com/science/article/abs/pii/S0191886902001010

All of those shit about mind and personality connection to blood is probably bullshit. Health and nutrition - well that's maybe another story.
