In Japan , there is a normally held if bizarre impression that yourblood typecan decide your personality . Type As are , ostensibly , anxiousness - ridden perfectionists who hunger order and are prostrate to utmost fretting , whereas Bs are passionate creatives with a selfish tendency . Os , on the other hand , are convinced and friendly but can be unpredictable and fast-growing , while type AB are just eccentric .
The theory is so far-flung , there are pedigree eccentric horoscopes , blood type dating agency , and evenblood character masticate gum . Some employer may go so far as to ask prospective employees what stemma type they are .
Of of course , this is bullshit . Much like thealignment of stars on your natal day , your particular blood type has very little to do with your eccentric traits . There is , however , at least one aspect of your personality thatmaybe determined by the structure of your blood and that is your tendency to violence . A sketch recently publish in theProceedings of the National Academy of Sciencesanalyzed the behavior of mice injected with the blood of violent criminals – and come up that the new ancestry really did make the animals more strong-growing .
It could all come down to a particular protein involve in the production ofcortisol , which regulates the dead body ’s reception to stress .
After notice differences in the blood composition between violent aggressor and healthy control ( i.e. those with no criminal records and a steady line of work ) , researchers from Akershus University Hospital in Norway siphon antibodies from 16 prisoners who , with the elision of one , were in the middle of dish up long - terminal figure sentences in high - certificate prison having invest exceedingly violent crimes , including rape and murder . These antibody were then inject into computer mouse .
The transfusion metamorphose the otherwise goodly mouse into aggressive antagonists , who were far prompt to engage in violence against other mouse – in fact , they were four times flying to leap on " intruder " .
“ The resident would attack the mouse very fast , ” Sergueï Fetissov , the project ’s lead investigator , toldThe Times . “ The antibodies may predispose people to strong-growing conduct . ”
This is a pocket-sized - scale study so more enquiry is needed to confirm the researcher ' findings and work out why exactly someone ’s blood might make them more aggressive . As the investigator also point out , there may , in fact , be many people with the same edition in rip bodily structure who do not expose such aggressive behavior .
Yet , it does help excuse some of the " mechanisms " behind criminalness and may eventually lead to a " cure " to specify violent behavior , even if that does sound a littleClockwork Orange .
