Work-related death

All professions have a chance of dying from a workplace-related injury. The chance is determined by a RandomSelection(_years, _population) function which takes two floating-point (float type) variables, _years and _population, as parameters. Without access to the source code, it's difficult to know exactly what the function does, but generally: The parameters for each profession are as follows:
 * 1) If both numbers are large, this is a low chance.
 * 2) If both numbers are small, this is a high chance.
 * 3) If _years is greater than or equal to _population, this is an above average chance.
