Sigh. I am speechless about this. Just a sad sigh. Barbie obsession

I had a psychology teacher in college back in late 1980s. She described what a real life Barbie would be like. She said she would have constant back pain, knees would become arthritic and would need surgery at some point, bad hips since the legs nor hips could support the trunk. She also said Barbie's ankles may collapse. Not sure if she was right on the biological aspect although it made sense. My teacher was very antiBarbie because of unrealistic expectations young girls could have.
