I asked the tallest person in my office (well over 6'7") how he managed when traveling. His answer 'generally miserable on flights, beds too short and often showers are set too low.'

Did he consider himself disabled as a result?

He said 'no' but predicted if he went the way of his father, years would bring him bad knees, neck and back problems and joint pain.

Would he then consider himself disabled?

He said 'no' at his father's current age of 60, but there's no way to predict the future.
