Bob Rutherford of Saskatoon, Canada, is 88 years old. When his wife passed away in 2010, he felt he had nothing left to do. His son suggested he help himself by helping others. As reported by the CBC, Rutherford built a high-speed knitting machine in his living room. He calls the operation "Socks by Bob."
How fast is his machine? "It could be knitting at 90 stitches a second," he says. Custom Woolen Mills near Calgary donates a lot of wool for the socks, and with the help of some "elderly" buddies, Rutherford has knitted 10,000 pairs so far, which he donates to homeless shelters in Saskatoon and across Canada. "Socks by Bob has given me something to do," he says gratefully.
