In the United States, conventional medicine consists primarily of drugs and surgery, which are the most widely used treatment modalities.
There are common established heights for table/counter surface and seating combinations. They are: Table height: 30in (750mm), with a chair at 18in (450mm). Counter height: 36in (900mm), with stools at 24 in (600mm). Standard bar height: 42in (1050mm), stools at 30in (750mm).
Bar stools are meant to be used at the portion of a kitchen counter that is stepped up (usually by 6 inches) from the rest of the counter, usually this portion is 42 inches high rather than 36. Bar-height stools are also the most common match for pub tables. Their seat height is normally 30 inches.
