What does your body say about you?

Hello Blog land!
Ok... So I've been pretty remiss in my lack of blog posting this summer, and I very sincerely apologize. As per usual... it's been kind of insane. However, as the summer winds down and fall semester classes are swiftly drawing closer I'm getting back into the swing of things. I promise.
I've spent the morning thinking about first impressions. You know what they say... a first impression is everything. But... I've also been thinking that we all make up our minds, gather our own first impressions within a few seconds of seeing someone. That leaves the majority of this impression to be based on sight alone - since that hardly gives any time at all to consider any attributes other than those purely physical.
So, let's say on Wednesday, September first, I walk into my sculpture class and upon entering the studio, I see a girl. Is she thin? Is she curvy? What judgments do I make of her based on her weight alone before even learning  her name? (Her body type could mean different things - I could be *more* inclined to make positive judgments if she is a curvy girl, or I could think that means she is too lazy to go to the gym, a couch potato etc) What about how she is dressed? What about her hygiene? Is she attractive?
I'm not entirely sure where I'm going with this right now... But I promise a followup blog in the near future.
