People look at me like I have 2 heads when I try to talk about some interesting person's personal finance blog. And I get questions like, "So, how long does he figure he can travel the world on $1.5M (or $600K, or whatever, the number never seems to matter, no one seems to think it can be done.) before he runs out of money?" Then I look at them like they have 2 heads and have to remind myself that not everyone understands the 4% rule. I usually just answer with something like, "I don't know, but he's living off the interest, so I guess forever." Because I don't have the energy to explain it to them.
