Inflation isn't necessarily the issue for retirees unless you are on fixed income but have expenses subject to inflation. The current problem is real rates are so low. If inflation was 10% and bonds were paying 15% it wouldn't be bad for those living on portfolio income.
In our case Social Security and TIPS are inflation adjusted, we have a low fixed rate mortgage, and our property tax is capped. Before too long we will both be on Medicare. I modeled high inflation in a spreadsheet before we retired and we come out ahead, so I'm not too worried, just plan to buy more TIPS and I bonds. Eventually solar panels, heat pump, xeriscaping, rain barrels, gray water system, etc. should get rid of most of the utility bills. We only buy one tank of gas every other month. We have cheap cell phone and cable plans. There just aren't that many expenses left for us to be subject to high inflation.
Do you live in an urban area? Do you not leave home often? Do you have an extremely large gas tank?
How are you only getting gas once every 2 months?
