In the ICD-10, the symptoms of hyperkinetic disorder are analogous to ADHD in the DSM-5. When a conduct disorder (as defined by ICD-10) is present, the condition is referred to as hyperkinetic conduct disorder. Otherwise, the disorder is classified as disturbance of activity and attention, other hyperkinetic disorders or hyperkinetic disorders, unspecified.
It depends on whether you are talking about an African or European swallow. The airspeed velocity of an unladen swallow is roughly 11 meters per second, or 24 miles per hour*, beating its wings 7-9 times per second (rather than 43). But please note that a 5 ounce bird cannot carry a one pound coconut.
Originally Answered: What is the air speed velocity of an unladen swallow? To be entirely dry and geeky: This question is a quotation from the popular comedy film Monty Python and the Holy Grail. It was asked by the Man from Scene 24 while Arthur and his Knights were trying to cross a rope bridge. If the man asked a question that you did not know, you would be cast into the pit.
