Out of curiosity, I googled it:
A way of life or style of living that reflects the attitudes and values of a person or group: "It was a millionaire's lifestyle on the pocketbook of a hairdresser" People.
I guess my mind hasn't changed since first posting. It does seem a perfectly innocuous, concise, word that only looses its neutral meaning with connotation. I think most words can be used to imply judgement if the speaker is, in fact, judgemental but, again, the "judgement" can also be in the recipients ear only. This reminds me of my days in the military when stating, off base, that I was a WAVE. To some, that said the lifestyle of a "whore"... and to others one of a patriot and, still to others, simply a profession.
