Flamboyant

Hello all, I didn't know where to fit the subject so I put it here. Sorry for my very poor English, I am French speaking. I'm wondering about the D antigen (ABO system & Rhesus system). I first consulted Wikipedia (not the most reliable, but the fastest), and then other French-speaking scientific communities, which are turning a deaf ear, without really getting an answer... I didn't understand absolutely nothing, not being a scientist... in fact, I passed tests concerning immortality ; and by "chance" or "without doing it on purpose", scientists found large amounts of D antigen in my body. This allows me to heal from severe wounds, and even death. Could a good soul shine a light on this famous D antigen in my lantern ? What is it and what is it for ? Thank you in advance and cordially, David This could be related to this jellyfish : https://en.wikipedia.org/wiki/Turritopsis_nutricula Nothing about a genetic relation between this "méduse" (in french) with a human body. Human immortals cannot return to childhood. We would be "stuck" at a completely different stage of maturation than Highlander syndrome. No report.
