We have one of those nearly-extinct COLA'd pensions (that is well funded) that covers all necessities and SS that I started at FRA a few years ago. The SS is nearly all gravy so half of that goes for luxuries like not paying much attention to prices in the grocery store, hobbies (R/C airplanes and DW's gifts for grandnieces and grandnephews) and other non-essentials. The other half goes to savings for new vehicles, roof, and other lumpy expenses. So far it all seems to be working, there's more there now than when we started.
We haven't touched the IRA or DW's Thrift Savings and barring unforeseen calamity probably won't until RMDs force us to. We'll probably just plow that back into savings, more out of habit than anything else I suppose. Gotta learn to Blow that Dough!
