A variable resistance cell and method provides a variable resistance response to a load factor, such as a load, a load rate, a strain, a strain rate, a pressure, or a deflection. A variable viscosity fluid is displacable between first and second chambers of an enclosure though an orifice in response to the load factor. The variable viscosity fluid has a viscosity that is variable corresponding to the load factor to vary an ability of the variable viscosity fluid to flow through the orifice. The variable viscosity fluid can be a shear stiffening material that increases in viscosity with an increase in a load factor applied to the shear stiffening material, a magneto rheologic fluid responsive to a magnetic field, or an electro rheologic fluid responsive to an electric field. The enclosure can be compressible between first and second positions. In the first position, the cell is responsive to a relatively larger load factor and has a first larger dimension in which a lesser amount of the variable viscosity fluid passes through the orifice into the second chamber. In the second position, the cell is responsive to a relatively smaller load factor and has a second smaller dimension in which a greater amount of the variable viscosity fluid passes through the orifice into the second chamber
