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)
Some key statistics include: On average, every day more than 8 million people fly. In 2013 total passenger numbers were 3.1 billionâsurpassing the 3 billion mark for the first time ever. That number is expected to grow to 3.3 billion in 2014 (equivalent to 44% of the worldâs population).
