I think my biggest piece of advice to people that are investing longer term is to not have any bonds. I don’t really do much international exposure, but I think doing that is way more reasonable than bonds.
Buffet and Bogle basically would advise you to just put it all in an s&p 500 index, I think if you aren’t comfortable doing that, then do what justwin describes and I bet he would be willing to give you his proportions.
But again, I cannot emphasize this enough, eff bonds.
