East Asians apparently have a higher percentage of Neanderthal dna than Europeans, with it going as high as 4%. It's hard to believe that at 2% it's greater than 99% of people, since 2% seems rather average for the average East Asian and the East Asian population being 1.7B or so. East Asians also have Denisovans dna as well.
I believe 23andme rounds down, so I could be at 2.49% and it would still show 2%. Anyways it's just a fun statistic based on probably not a proportionally representative sample of the entire human population, but what they have on hand.
I get a few strands of really really thick hair on my head. Sometimes in my nose too.
Also, I once had a single piece of hair that turned from fully black to fully white back to fully black in a span of maybe a dozen cm. And a few strands that turn orange-reddish, all for no apparent reason.
Though I'm just guessing this is related, maybe it's pure chance.
