How active is she, and how much space does she have? There are people who spend a lot of time buying things at yard sales and estate sales and then selling them for profit on EBay. Is there a college or university anywhere near her? Many of them will let retirees audit classes for free or a tiny fee. If not, maybe she’d enjoy a MOOC or two?
