Well... I remember hearing a woman who said that, when she was separated, she started going to a massage therapist, to avoid touch-hunger. And I thought that was a wise decision, even though it could be a luxury or indulgence, insofar as she maybe didn't have any specific problem she was trying to solve.

So, I agree with you, but even as something one *could* call a luxury, I still see a greater value in it. (And I sometimes kick myself for not thinking of it myself, at times when I've been human-touch deprived.)
