Up to 6% of some European Blood is Neanderthal in some areas

If your ancestors are from Europe you could have up to 6% Neanderthal blood. In some ways this is a good thing because it means you have an incredibly powerful immune system because Neanderthals had to survive without a lot of help, clothes or medicine. So their immune systems had to be the best of all the bipedal human types on the planet. So, if you have the 6% Neanderthal blood from Europe your immune system likely is quite amazing.
