In general terms, I believe that from birth to death everyone has the opportunity to experience the wonders of ability, as well as the frustrations of inability. We all experience the diversity of the human mind. For some the extreme zones are infrequent or short visits, while others are trapped in the extremes, or are in a leap frog conundrum between them. How we face this helps to shape our character, effects our general well being, contributes to our stress levels and determines our attitudes to life long learning. 

While the majority of people are not negatively effected by this and develop self sufficient coping strategies, not every one is so lucky and able to do so. People most often at either extreme of the ability / inability spectrum are recognized as having 'special needs'. Special needs are most commonly associated with people with disabilities. Yet the majority of people who have abilities, generally also have disabilities, often hidden from sight. We fail to see the weaknesses in those with abilities, just as we fail to recognize the strengths of those with inabilities. The difficulties are not always medical, or biological, they can also be systemic, situational, sociological or political. 

People are all too often restricted to one end of the spectrum and community prejudice because of stereotyping, which denies their recognition in the other. The degrees of 'ability' and 'inability' are relative to the individual, not to the stereotype.

Currently, the difficulties of the lack of community, shared experiences, the uneasiness of belonging vs alienation, combined with the feelings of isolation in the world, play a big part on the frustrations, relationship break ups, self-harm and suicide statistics, where increasing numbers are a sign of our times.
