Any investment advice besides "buy gold bars"?

I've been following a lot of Peter's stuff. Does anyone know what advice Peter has for people that are trying to save for retirement besides "buy gold"? I've heard him say that international stock in other countries is underpriced due to how strong the dollar is. But he's always been pretty vague about it. Personally just not interested in owning gold bars. What do ya'll think?
