Thank you, Bakers!
Is there any genetic benefit to harvesting stem cells from a fetus/infant/cord/placenta that are genetically part yours? Is there any difference in the stem cells that would benefit you individually? Or is that contrary to the whole point of stem cells?!? Just wondering if there would actually be some incentive for these psychopaths to impregnate someone themselves for the special harvest. OMG, please clean the world of such things, I can barely stand to think and write about it.
I believe that there has always been a pretty wide variety in when development kicks in, but it seems that many more girls are hitting puberty earlier, probably due to estrogen influencers in foods/plastics.
