Real Women vs. Barbie
Barbie (as a human)
Barbie's body would have room for only half of a liver and only a few inches of intestines, as opposed to the usual 26 feet. The result: chronic diarrhea and death from malabsorption & malnutrition.
Barbie's neck is twice as long as the average human's which would make it impossible to hold up her head.
Barbie's waist is the same circumference as her head.
Barbie's legs are 50% longer than her arms, whereas the average woman's legs are only 20% longer than her arms.
To look like a barbie proportionally, a healthy woman would need to add 61 cm to her height, subtract 15 cm from her waist, add 13 cm to her chest, and 8 to her neck length.
If a woman had the same measurements as Barbie, she would not have enough body fat to menstruate (and obviously to have children).
There are 3 billion women on the planet who don't look like Barbie; only 8 women come close.
Barbie would be unable to walk upright (she would need to walk on all 4's): her feet are so proportionately small that her chest would pull her perpetually forward onto her toes.
Now, don't you feel better?
