Forget about leaving the workforce at age 63.

"70 is the new retirement age," personal finance maven Suze Orman writes on Money. "Not a month or year before."

She points out that Americans are living longer, meaning your retirement savings need to last longer: "You likely have plenty saved up to breeze through 15 years or so of retirement. But, people, if you stop working in your 60s, your nest egg might need to support you for 30 years, not 15."
