Details?...What details?...
*snort*
I can understand most of what you write, so yes, it IS "instruction." And some days, that's a real job...that understanding stuff. (New research indicates that the brain is affected by CFIDS to the point of slowing down...which explains why some days, I don't want to drive.)
I can identify with this. I've noticed when I am tired, that my highway driving slows down.
It feels fast enough to suit me, but the speedometer indicates I'm doing the legal speed limit, or slightly less -- a radical departure from my normal behavior.
