Jonathan Clements, personal finance columnist: "Nobody knows how financial markets will perform in 2016, so focus on five financial advantages that we all possess: First, human capital, which is our income-earning ability. The more income we earn, the less dependent we are on the financial markets. Second, we know how we reacted to earlier market declines, and we can use that to guide how much risk we take today. Third, we know when we'll need cash from our portfolio, and we can make sure we get that money out of risky investments and into safe investments well before the deadline arrives. Fourth, if we're living off our portfolio and the market declines, we can always limit the damage by cutting back spending. Fifth, if you don't want to depend on stocks and bonds, get off the market rollercoaster and lock in a healthy stream of lifetime income by delaying Social Security and using part of your savings to purchase plain-vanilla immediate-fixed annuities that pay lifetime income."
