Here's a headline that had me heading for the dictionary:
"Seven Mindless Ways to Earn Extra Cash When You're On the Road"
Mindless? I wondered whether it had a meaning I wasn't aware of. But the dictionary offers these:
acting or done without justification and with no concern for the consequences."a generation of mindless vandals"
synonyms: stupid, idiotic, brainless, imbecilic, imbecile, asinine, witless, foolish,empty-headed, vacuous, unintelligent, half-witted, dull, slow-witted,obtuse, weak-minded, feather-brained, doltish, blockish; More
not thinking of or concerned about."mindless of the fact she was in her nightie, she rushed to the door"
synonyms: indifferent to, heedless of, unaware of, unmindful of, careless of,insensible to, blind to"she was mindless of the consequences of her actions"
The suggested ways to earn cash included renting out your home or your car while you are away, so I guess they meant methods that didn't require your attention once they were in motion. I can't think of a single word that encapsulates that (but mindless isn't it). If you have a candidate, let me know!
