I remember being curious about things when I was a kid, too.
They were solid and did not bend, a throwback to the vintage dolls of the early sixties.
I have done it twice now.
This body sculpt somehow looks cheaper and less well-defined than the original sculpt to me.
My current housemates are Cindy, my 14-year-old Staffy-Lab X dog and Polly the world's most unsociable cat who is seven.
I therefore think that you are right with the fact that children are obsessed with the human body and I think that fashion and tv have been detrimental to this as they want to grow up to early.
