It could lead to a long period of pain" The art of language - beating the S&P 500 since the golden year 2000. The other side of the coin - if you bought in 1980, you wouldn't break even until 2007. That's 27 years – going all-in young, only to find yourself still underwater at retirement + facing delayed retirement. *image by: http://goldprice.org
