Most researchers believe that Olde Robert Selfe was the ancestor of most of the Self family in America. Arriving in Virginia in the 1600s, Robert Selfe appears to have been descended from Walter Selfe of Cripplegate, London, England. The name Self is thought to be a shortened version of Seawolf, dating back to the early Viking voyages along the English coast.
A stress reaction is the lowest grade of the three levels of bone injury. A stress reaction is essentially the early stages of a stress fracture. This occurs when the stresses affecting the bone occur at a faster rate than the rate at which the bone is able to rebuild itself.
Stress as a response model, initially introduced by Hans Selye (1956), describes stress as a physiological response pattern and was captured within his general adaptation syndrome (GAS) model (Figure 16.3). This model describes stress as a dependent variable and includes three concepts: Stress is a defensive mechanism. Stress follows the three stages of alarm, resistance, and exhaustion. If the stress is prolonged or severe, it could result in diseases of adaptation or even death.
