What About Buffet?

Here's another great post by Jason at Dividend Mantra:

Buffet's advice to his estate manager:

"...and 90% in a very low-cost S&P 500 index fund. (I suggest Vanguard’s.)..."

Besides that Jason explains clearly for Newbies like me what exactly fixed income is.

Interesting, the German MSCI index fund supposedly outperforms Vanguard's S&P 500:
