Rudy Riske started a hillside flower garden at age 85, in a patch of swampy weedy public land. It's in a rough neighbourhood in Toronto, notorious for many social problems. He pulled weeds and thorns, built terraces, endured thievery, and at 95 still goes out twice a day, seven days a week.
I love this. I hope I'm doing the same at 85 -- let alone 95. Go Rudy!
