I bet there are homeless shelters in your general area. Homeless shelters in my state (some are only about 40 min drive from me ) always looking for volunteers in the kitchen. It’s not too difficult but rewarding and gets you out of the house and you meet other volunteers. Often single women. Or anyone in fact. You are in your 60s not 90s. Most of my girlfriends are in their 60s. It’s not old
