Well into his 800s, Yoda is the oldest member of the Jedi High Council, as well as its most deeply perceptive Master. Yoda has quietly visited hundreds of worlds on his own, spending years learning different lifeways and appreciating the infinitely variable nuances of the Force. His experiences have made him cautious and reflective.
