Looks to me like there are two groups here. One includes those who travel and eat out a lot, who have seen their expenses fall. Then there are those like me who have seen little or no change, perhaps even a small rise in expenses because we rarely if ever travel or eat out. Those of us in that group may be paying slightly more for groceries because store sales are gone, without any offsetting savings elsewhere.
Retired in late 2008 at age 45. Cashed in company stock, bought a lot of shares in a big bond fund and am living nicely off its dividends. IRA, SS, and a pension await me at age 60 and later. No kids, no debts.
