Tao Porchon-Lynch, recognized by the Guinness World Records as the “World’s Oldest Yoga Teacher”,turned 100 last month. The world-renowned centenarian from White Plains celebrated her 100th birthday with closest friends at an event space in Westchester. The celebration, over brunch, included dancing and singing. “She’s looking forward to more yoga and dancing and traveling and spending time with friends,” said Susan Upton Douglass, of Scarsdale, who attended the event. A broken hip in February has meant putting her regular classes on hold for the time being, but it has not slowed her down.
