I am your age, happily married and owner of a small software-consulting-company. Half of your networth.
In the years mentioned capital flowed into gold, because of negative real cash yields. For money there is currently no real alternative asset class to stocks, cash looses to inflation, gold is above its inflation adjusted average price and bond yields are much too low to be an alternative.
But the thing is, when you invest bottom-up and not top-down every piece of macro information is noise in the wind. Look at 1999 when the market was really overvalued, from 2000-2002 cheap stocks outperformed the market big time, so it is probably very good for cheap stocks if the broad market is really overvalued. :)
