So I live within my means and hope that some of it is still there when I'm older! So far, so good since Trump got into office.
But you could tell your 401K admin to sell your stock funds and put the money into a money market fund, securing the full market value of your stocks in cash - if you wished to do so.
You could also take money out before age 59 1/2 through a 72t plan.
I do not personally recommend either option.
