What do veins say about a person?

I be we have all noticed a lot of different peoples' bodies emphasize different veins. For example: "Why does that person have a vein branching out of that vein on their neck? I don't have it." So what do veins say about a person. What would a lot of veins say on a girl, guy, skinny, heavy, lean, built person? What does branching of the veins indicate? More specific: Can you tell how strong a person is by noticing their veins? Can you tell what they do for a living from noticing what veins are more or less emphasized? What about heritage? Is the design in our veins genetic, and traceable only to a certain ethnicity? I can go on and on asking these kind of questions. Please, don't try to answer all of these questions (if you don't want to), but a generalization would be appreciated (not equally as a more detailed answer answer conveniently). Thanks
Answer:

There are way too many factors that affect http://en.wikipedia.org/wiki/Vascularity for you to be able to safely conclude anything by just looking at a person's veins. Some of these factors are: body fat percentage hydration water retention skin tone genetics certain types of steroids / drugs (I say certain types because I don't know enough about them to know what affects vascularity) The Wikipedia article linked above does go into a bit more detail.
