Cherry angiomas, also known as Campbell De Morgan spots or senile angiomas, are cherry red papules on the skin. They are a harmless (benign) tumor, containing an abnormal proliferation of blood vessels, and have no relationship to cancer. They are the most common kind of angioma, and increase with age, occurring in nearly all adults over 30 years.

from Wikipedia, the free encyclopedia. Viscosity is a measure of the resistance of a fluid to deformation under shear stress. It is commonly perceived as thickness, or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is thin, having a low viscosity, while vegetable oil is thick having a high viscosity.
