Three types of opioids are classified by the effect that they have on the mu receptors on cells. They are the full agonist, the partial agonist and the antagonist. As used here, an agonist is something that stimulates or produces an effect. Agonist is derived from the Late Latin agnista which means contender which is derived from the Greek agonists which also means contestant which came from agon which means contest.
So i make that 0.05%. And the US has 250,000 pilots for 250,000,000 people so thats your 0.1%. And given these are two of the most pilot/aircraft dense countries in the world then for the 6 billion people in the world there's probably less than 1-2m pilots. (But that still a scary amount of ego for one small planet)
Approximately 1 billion people travel each year by air on the many. domestic and international airlines. On U.S. air carriers alone, it has been. predicted that in the coming two decades, the number of passengers will double. A global increase in air travel, as well as a growing aged population in many. countries, makes it reasonable to assume that there will be a significant increase. in older passengers and passengers with illness.
