Is knitting good for you?

Is knitting good for you? Probably, but it's not good for your teeth if you chew your Aero needle like that. Maybe she's trying to give up smoking.

From Weldons Double Knitting for the Family, early 1950s:

"Is knitting good for you? Why do you knit? You want a new jersey? It's economical? Yes, but most of us knitters like knitting, too. The easy, regular movement is soothing and restful - provided we have the right materials. That's why so many prize-winners use Aero - the smooth grey needles, with long rounded points that won't split or soil even the lightest wool. Try Aero knitting needles yourself, and see what smooth professional results you get."
