a general reply to the replies of my original post.. When I mentioned mental stimulation I should have emphasized the kind. Stimulation can trigger many mental activities of course - reasoning, analysis, entertainment, contemplation, etc. It's this unbalance, a majority of entertainment that worries me. Don't get me wrong, I love entertainment and mindless stuff and I think it's part of healthy life! So, I don't think it's over stimulation per-se, but a gross unbalance of kinds of stimulation.. But I'm moving away from my main point/question which I think is: can we off-sourcing most our mental abilities without major negative impact on our health? It's not just these mental abilities aren't needed. What are the consequences of a brain that barely uses its memory? What are the consequences when you almost never use your brain for any challenging task? Maybe this will lead to all sorts of mental illnesses... These are the things I am really curious about
