Unnecessary Body Parts
We have a number of body parts that are, well, useless. Here are some facts about the body parts we don’t actually need.
800px-ToesCoccyx: This collection of fused vertebrae have no purpose these days, although scientists believe it’s what’s left of the mammal tail humans used to have. It may be useless, but when you break your coccyx, it’s still painful.

Wisdom teeth: This third set of molars is largely useless, doing little beyond crowding the mouth and sometimes causing pain.
Vomeronasal organ: There are tiny (and useless) chemoreceptors lining the inside of the nose.
Most body hair: While facial hair serves some purposes, the hair found on the rest of body is practically useless and can be removed with few ill effects.
Female vas deferens: A cluster of dead end tubules near the ovaries are the remains of what could have turned into sperm ducts.
Male Uterus: Yeah, men have one too — sort of. The remains of this undeveloped female reproductive organ hangs on one side of the male prostate gland
Appendix: Yep, your appendix is basically useless. While it does produce some white blood cells, most people are fine with an appendectomy.

Last time we discussed the Body Language of a Woman, the key take home was that women are culturally becoming more like men in behavior.
A Woman's Body Language is Critically Observed
The next step in observing and understanding reactions to women is the fact that those behaviors are generally a net negative or large negative for women.
Men and Women are as different as night and day.
Men and women are viewed very differently by others.
A man performs behavior X, and he is seen as one thing. A woman does the same behavior X, and she is perceived dramatically differently.
A key challenge women face is the temptation to emulate men and anticipate the same response from those observing her.
How Are You Judged?
From the second you notice someone, you judge them. You judge them innocent or guilty of all kinds of traits and characteristics.
Body Language of a Woman It's from this vantage point you'll learn how most women are perceived performing different kinds of behaviors.
1) Voice Judgments - As soon as a woman begins to speak, judgments expand and solidify. Here are typical characteristics and how they are experienced by others:
a) Nasality - The Boston/New England woman is at great disadvantage if she doesn't consciously retrain herself to speak with a more Midwestern tone. Nasality is perceived almost universally as bad.
b) High Pitch Tone - Women who speak at a high pitch are seen as dynamic and extroverted. There are minor negatives here but overall, this is a high positive.
c) Pompous/Bombastic sounding voices in women cause her to be seen as humorless but lively. Net: Neutral.
d) Throaty sounding women are perceived as ugly, boorish and uninteresting. Net is a high negative.
e) The Tense voice in a female is perceived as young and emotional.
f) The Flat Voice in women is perceived as negative.
g) The Thin Voice in women is perceived as emotionally and socially immature but it is associated with an increased sense of humor.
h) The Breathy Voice in women is perceived as feminine and shallow.
