@Marshall Sutherland (Posting with Hubzilla) so in essence, they're delegating their thinking, then? I know such people, indeed, they themselves, think themselves, some of the most wise. I don't see it myself, but I'm a sceptic and a cynic, by nature.

I love doing my own thinking though, since doing so, may indeed, stave off atrophy. That's my rationale anyway. I think, that thinking and shifting the different possibilities of any focused topic, or subject, may be one of my favorite pastimes. The thought of having someone else or indeed, something else taking over that duty, is an uncomfortable one, one bordering on paralysis.
