I don't know the exact numbers or percentages. What we do know in the United States.... There was an article by a couple of economists from Princeton, who were looking at the causes of death and saw that it was particularly white middle-aged men in America who had an increase in opioid overdose deaths. As we were hearing from the previous speakers, it is much higher in rural parts of the United States than it is in urban parts, believe it or not.
Again, I think local data are really important. With white middle-aged Americans, they were talking about the epidemic of despair. It isn't just physical pain. For people who have had jobs in the construction business, forestry, agriculture or whatever, when those jobs move away or people lose them, they're left with economic despair, as well as physical pain.
