Expecially for BlessOTMA, but for everyone interested in:
i've met my brother in law today (he's studying to become a doctor) and he told me he has made research about arsenic injections; he says he's sure it's not good for health at all. He explained that every poison strains everyone's liver and loins; it could kidney failure and serious hepatic problems. I told him about Olga, and he says it's quite certain that the poison has someway "ruined" her skin, and her excessive thinness during captivity could be caused by the injections. I explained him that during captivity she had no injections, as far as we know, but he is adamant: it takes a really long time to human body to completely eliminate a poison, even if injected in small quantities.
So he's quite sure that if Olga looked like an old woman being only 20, it ALSO because of the arsenic. I said ALSO, because, as we already told, she was depressed and hopeless, too, and this played a great part in her health.
