Well, for a start, I think copying the OP's list and highlighting traits is a good idea. After all, it's all we have. I've added a few more traits/experiences.

Here are the scientific FACTS about” Rhesus Negative” blood groups:

• Most have stronger Immune systems.
• Most have Autoimmune Conditions and the HLA-B27 genetic marker. (I dunno)
• Most have fair skin and light eyed, in response to having Melanin imbalances and Vit. D Deficiencies
• Most process CO2 more efficiently (I dunno)
• Most tend to have Iron/Copper imbalances
• Missing the RhD protein that acts as a barrier on the red blood cells. (I dunno)
• Pregnancy issues and complications with the clashing of blood type within the fetus. (I dunno, hubby O-)

NEW:
. Birth control pill issues; ineffective, or causing thrombosis
. fast healing time for wounds
. medications/supplements can be ineffective; sensitive to side effects
. overly emotionally sensitive, prone to mild depression
. allergic to preservatives in food
. allergic reactions are immediate
. healthy sex drive under ideal circumstances
. hormonal imbalances
. freckles at some point in life
. superior sense of smell
. superior sense of hearing

Now given that negatives are missing this “ RhD protein” around their red blood cells. Could this be that the protein acts as a barrier to protect the person from the effects of the environment? Could this be why most negatives have psychic abilities there is not a protein barrier, so could things we don’t yet understand channel into us giving us these strange abilities? As you can see most RH NEGS are almost seemingly “allergic” to the environment we are in- And by that I mean the SUN. It’s like we don’t work properly in this environment.. Can’t bare children without medical intervention, and all the other things I mentioned above we either completely lack it or we are overly producing defenses to it.

Here are a few “fun” facts shared by many within the Rhesus negative groups (I can say for MYSELF alone that these are FACTS of negatives reality But I don’t want to share my “weirdness” at this moment):

• A feeling of not belonging
• Truth seekers
• Sense of a "Mission" in life
• Empathy & Compassion for Mankind
• An extra rib or vertebra.
• Higher than average IQ
• ESP Ability
• Love of Space & Science
• More sensitive vision & other senses.
• Increased of psychic/intuitive abilities
• Cannot be cloned (I dunno)
• Lower body temperature
• Higher blood pressure (some say lower either way one extreme to another never quite right)
• Predominantly blue, green, or Hazel eyes
• Red or reddish tint to hair color
• Increased sensitivity to heat & sunlight
• Unexplained Scares
• Piercing Eyes
• Tend to be Healers
• Empathetic Illnesses
• Ability to disrupt electrical devices
• Prone to Alien Abductions
• Experience unexplained phenomenon
• Physic Dreams and/or Ability
