Quote:Creatures that regenerate limbs and organs have stem cells that keep this ability throughout their life cycles. If a salamander’s leg is cut off, for example, its stem cells rush into action and form a fast-growing mass of undifferentiated cells called a regeneration blastema, which eventually will differentiate and form the various structures of a new limb.
But like most mammals, by the time we’re born, those pluripotent cells are replaced by somatic -- adult stem cells, which can maintain and to a limited degree repair the part of the body in which they’re found.
But humans can’t make an entire new arm. “There must be something in humans that prevents the regenerative process from going that far,” Gardiner says.
Some scientists think it may be an evolutionary tradeoff.
“If an amphibian chews off one of its arms, it could hide away for weeks without eating and regenerate,” Enrique Amaya, a developmental biologist at the University of Manchester in Great Britain, recently told BBC News. “That’s out of the question for an animal whose high metabolic rate requires it to feed constantly. It has to heal quickly and dirtily.”

I'm not 100% sure why, at the age of 2,5 or 8 I wanted to be a girl, but, these days and for the past 30 to 40 years, I'd say it's just that I think of the female body as being very beautiful and I'd MUCH rather have that: those gorgeous tits, that cute little pink slit, those sexy legs, that sweet ass, that long gorgeous hair, that beautiful face, that wonderful body that can do such cool things (having periods, taking sperm inside of it and making babies with it, making milk) than to have this boring klutzy-looking body that just has muscles and a dick that rarely ever gets used for it's intended purpose. To me, it's kind of like going from a car with a dashboard that just has a radio and a cigarette lighter, to one that has a music system with 5.1 Bose speakers, things that can make the car change colours at will, jump over other cars, make the roof open or close, move the steering wheel from the left seat to the right and a small pool in the back, etc.. Mind you, I'm by NO means a car person, I'm just trying to use terms that most of you would easily understand rather than my own terms, those of drumming, which most of you wouldn't get at all.
I see a pretty girl on the street or anywhere else, really, and, one half of me wants to fuck her, the other half of me wants to BE her!! I see those gorgeous tits of hers and I want SOOOOO BADLY to have those on MY chest!!!! Or, I see her pretty cunt and ACHE to have that between MY legs!!!!
Starting from the age of 9, a girl's body goes through so many wonderful and exciting changes! In the meantime, during that spate of time, all a boy's body does is sprout hair, grow muscles, get a deeper voice and a dick that's fully loaded with sperm he'll probably never use. How boring!!
So, that's kind of the very short version of why I've almost always wanted to grow tits and/or be a girl. How about you?
