I don't think about it at all! The dollar will remain the world's "reserve" currency as long as our country remains the largest, strongest, most trusted economy in the world. If that ends, we -- all of us, not only seniors -- will have a lot more to worry about! You get paid in dollars, save in dollars, and do retirement planning in dollars. No reason to do otherwise. And if you want to "hedge" your bet on the dollar, you can buy some gold or shares in a mutual fund company that buys gold mining stocks with a small, less than 10%, portion of your retirement funds.
