the standard is unable to do the tasks of any job due to objectively documented limits in your ability to perform physical tasks, communication tasks, tasks requiring manual dexterity, analytical or accounting skills for example. People are seen as unable to perform the tasks of the job when their objectively documented problems interfere with work tasks they might reasonably be able to do based on education and past work history or their potential to retrain to work compatible with their "transferable skills". high school graduates are expected to be able to do "sedentary work" by virtue of their education.

key works are "objective medical evidence" and "tasks of a job". this does not weigh someone's ability to get a job nor the availability of the work in your area. If you are a high school graduate and under age 50 you are considered able to do sedentary work. sedentary is the lightest type of work in so far as physical tasks are concerned. Other aspects of work performance can be measured with memory, intelligence testing, neuropsychological testing, range of motion and dexterity measurements to name some of the objective evidence used to document disability.
