"get out and about" meaning

Solution 1:

[Out and About] refers to physically experiencing something beyond one's ordinary environment, to enjoy for the pleasure of it or learn what can only be learned beyond one's ordinary environment. The 'out' refers to [out of one's ordinary environment] and the 'about' refers to more than one other place or an extended period of time. Out and About would not include running to the grocery store alone, or running to the end of the driveway alone; it requires multiple places or an extended period of time/experiences.

As for requiring 'people,' no it does not require that. It's focus is more on what happens within a person when they do it, not who or what they will affect when they do. People can enjoy or learn from many things, including other people, but they can enjoy and learn from 'getting out and about' with noone around too.
