A wide range of drugs used by too many for too long.
Back around 2000, I had retired from the military and moved to mil-contractor work. I sat in a IT room....four young female airmen and one day...the subject of SSRIs came up (Prozac is among the group in SSRIs).
All four were prescribed SSRIs in high school and the Air Force was continuing their prescription. All four had concentration issues...limited ability to make rational decisions...lousy sleep hours...anxiety issues. I simply asked...how many associates in high school were getting same drugs (they figured one-third of their friends).
My only suspicion today...if you had one-third of high school kids looped-up like this, then they can’t concentrate or perform routine testing. The system has lessened the tests, and they progressed on through college with the same problems, and the college lessening what they teach.
In the end, you are surrounded by dummies (even doctors) who can’t perform at the level required. Reminds me of that movie ‘Idiocracy’ (2008).
