The off-topic thing is hard to answer completely but I can mention my own shortcomings, that can lead to this.
I did donate my car, due to attention wandering, but haven't looked at the health treatment reaction, to such in general.
ADD is accompanied by a wide wide interest, often sparked by only brief stimulus.
An example shows this, as I have two examples, from today:
1.). Passenger Bus side exits. I just noticed, that an automobile system in the UK, while having the 'other side', when moving, that is, the left side of the road (driver's left) is the correct side, while right side for some other countries).
No need to delv into the details, there.
But I realized, watching a BUS let out passengers, that, naturally, they exit out from the LEFT SIDE, of the vehicle.
Had to chuckle, at my own ignorance, but I thought, immediately, that the manufacturing then had to cover both type of roads, and vehicles.
Sounds really stupid, to need even bother, toesrn such an obvious necessity, BUT; I did find surprise there. That little episode was a result of being hyper-sensitive to my own instincts, for CURIOUSITY.
The other item was sparked by a science show, playing there while I worked;
That was discussing milk cows and the calcium and other vitamins obtained.
What my question then was...(Is), Do cows obtain vit. D by way of exposure to the sun ?
That's a really nice question... (Do they ?).
See what I mean ? Often can't shut it off,...so I've tried being an inventor. Perfect fit, and I have pretty good tolerance for hardships, (as long as no family or animals suffer along side).
