I enjoy occasionally being able to rely on the old stereotype of being "blonde," when I want something explained more or in a different way, because it affords some humor and helps me reach my goal. Generally though, I think stereotypes are bad, because giving them any credence prevents one from looking beneath the surface for understanding. Stereotyping is a lazy way of perceiving others. There is nothing about my hair color that gives you clues about my personality, level of intelligence, or depth of feeling. At best, if one has gray hair, you may be able to guess they are no longer in their twenties, but even then, you'd sometimes be wrong.
I can understand the interest. I find astrology interesting. I like symbolism in general. I just don't give it much credence
