I have no idea. I do come from a multi-national family starting down from Greece up to the European part of Russia but I never bothered researching. I don't care where my body comes from. It's going to go where it came from...
Having said that, I keep dreaming about Japan and living in Japan. I've never been there. I have no interest in Japan when awake.
In one of my dreams I was a woman married to a fisherman and living in a hut. I saw myself as an aging 40-50 year old woman who really loves her fisherman husband. No joke. He was just about to go out fishing and he asked me to go to the market during the day to buy him new flip flops. It was one of those lucid dreams in which you are aware you're dreaming while dreaming....So I thought of asking him which year we were living in. He said 1950. When I woke up I went straight to internet researching if there were flip flops in Japan in 1950 to prove myself it was just a dream....Well, stupid me then finds out flips flops were exported out of Japan after the WW2 and became really popular since then. I swear I didn't know this bit of info about flip flops before that
That I suppose explains my love for fish
As for somewhat interesting family history, my grandma had 3 husbands. The 1st one died in the war in a submarine which was ordered by the military to sink itself with it's passengers to avoid being captured by the enemy. All were regarded as heroes at the time apparently but only the families were told how they died and why they died. The story ,as of yet, has never been made public. Her 2nd husband was tortured and killed in prison by the communists for giving grains to the poor out of the common communist's stored supply. This happened after the war. Her 3rd husband is the one I know, not my real grandfather but I regarded him as such. He was a veteran from the war with a drawer of medals and a wooden leg. He was super strict. If you were late on the table for dinner at 7, even by a minute, you might as well not sit
My grandma considered herself really unlucky in life and cursed to be alone. During the war and after, women did all the heavy work due to lack of any men. She outlived all her husbands by decades. The funny thing is, she nearly died when she was young. She was brought dying to a person, who would now probably be called a naturopathic physician. He gave her some herbs and diet to follow and she miraculously recovered. And for the rest of her life she didn't even know what blood pressure or cholesterol is. She died peacefully in bed when she was 92, up until then flying like a rocket doing chores.
