The Answer Is 42

We all know the answer to the ultimate question of life, the universe, and everything, is 42. And we know the best approximation of this canonically unknowable question is "How many roads must a hu/man walk down?" What does that really mean in practice? What does it mean to be a human who has walked those 42 roads? What might those 42 roads be? And does it matter HOW we walk them or simply THAT we walk them?
