South Bay Seniors surrounded by a sea of silicon may have a lot of catching up to do with their tech neighbors. On Saturday January from10-2 you can smarten up at the Avenidas Tech Faire. Access information about smart watches, 3-D printers, robots, personal transport vehicles, video games and staying safe online. Free. Avenidas, whose mission is to “re-invent aging” is a great resource for Peninsula fossils with classes on housing, finance, wine tasting and (let’s admit some of us need it) driving.
