When I was "growing up" there were no computers or cell phones, television meant watching four networks. Then..."UHF" came along and three more channels were added. One's telephone transmission was apt to be over a "party line." Meaning, your family shared the line with another family and if you picked up your receiver you could hear the conversation of the people who shared your line. Sometimes, you'd have to interrupt them to ask if they were almost finished speaking so that you could make a call. Progress was achieved when you could afford to have a private line. Then REAL advancement came when "party lines" ceased to be.
Newspapers ruled. They were packed with stories and the Sunday edition weighed "a ton." For "paperboys" like me, it was the hardest day. Music came over your favorite radio station or on your turntable (we called them record players or victrolas), via records that were either 45 RPMs, 33 1/3 RPMs, or 78 RPMs. RPM stands for revolutions per minute.
Families ate dinner together. Food wasn't processed as it is today, there were no GMOs, and...the days events were actually discussed at the dinner table!
ADHD, as we know it, wasn't around back then. Perhaps it was because there were relatively so few things diverting our attention. Folks who did numerous things, seemingly at the same time, weren't thought of as multitaskers, they could just do lots of things "at once."
So how did we become societies filled with ADHDers? Easy, we created a "world" that has countless things vying for our attention. We drift from one thing to the next, often without finishing the first, because...we are "pulled away" by something new, "more important" more attractive, more interesting, or more entertaining. The choices we have today dwarf those of 40, 30, even 20 years ago. In fact. it's hard NOT to be diverted! Yet...leave it to the pharmaceutical industry to develop drugs to control ADHD and other related "ailments."
I have an easier solution. Slow down, don't look at your electronic devises on a constant basis, clear your mind, speak with your friends and family, relax more, stress less, and have fun. It'll save you from having to buy more things you think you "need" that you really don't, and...it may even cut down on your prescriptions too!
