”Home” and “away” lost all meaning long ago, becoming a false dichotomy. “Furthest” is likely presumed to mean the most distant in space, but that is not always the greatest mental distance. Sometimes a place changes while you were away, and that shift through time becomes the most jarring distance.
That depends on how you define “home.” If by home, one means the place I’ve lived for the past decade [Bangalore, KA, India,] then its antipode is in the eastern Pacific Ocean – off the coast of South America. This would make the farthest I’ve been from home: Lima, Peru. If, however, one means the place I was born and grew up in [i.e. Northwest Indiana in the USA,] its antipode is in the Indian Ocean – west of Australia, and the farthest I’ve been would probably be the southern tip of Bali, Indonesia.
Either way, one could say that I’ve never been far from home (despite having visited 40-some countries over all continents except Australia and Antarctica.)
