"In Silicon Valley's youth-obsessed culture, 40-year-olds get plastic surgery to fit in. But IDEO, the firm that famously developed the first mouse for Apple, has a 90-year-old designer on staff. Barbara Beskind says her age is an advantage. "Everybody who ages is going to be their own problem-solver," she says. And designers are problem-solvers. Beskind speaks while sitting on a couch at the open office space of IDEO in San Francisco. She commutes to the office once a week from a community for older adults where falling is a problem." - Todd Hoff
