While I agree with your first sentence, I strongly disagree with your second. If someone is only "looking at stuff and eating" as they explore the world, then they have given up on exploring themselves (maybe temporarily, maybe permanently). There is plenty of opportunity and reward for growing ("exploring oneself") when you're older, and choosing not to is simply the path of least resistance that many/most people seem to take. Lots of younger people seem to think that the spirit of life starts to die after some age (30?) or life event (having kids?), but based on people I know who have passed these milestones, that is completely not a fait accompli. Quite the contrary.
