Ask HN: Mother (66) retired, bored and remote. What to do?

My mother recently retired. She lives in a remote location (very cold most of the year), but has good internet. She is used to being productive, and is mostly bored staying at home all day (husband works and supports).

She asked me if there are ways to make a small amount of money online and to stay mentally active/ not bored.

Does anyone have any hints? What are your parents doing at home (digital or otherwise) to stay entertained and sane?

Thanks!
