Yeah, RMD's are going to hit hard once that time comes because we haven't touched our 401Ks, and regular IRAs. Thankfully I had started a Roth IRA but it's not flush with cash. At least (not yet anyway) they don't have any RMDs on a Roth.
The problem with years of pack-rat style of saving and being financially "responsible" has really screwed up our psyche. We suffer from "Savings PTSD". Now that we have a healthy nest egg, we don't really know how to allocate it without feeling like we're just blowing it on something we don't really need. I mean, we still owe 0.00% interest on her car loan, I owe $583 on the 3.1% truck loan I'm going to end up paying off WAY early, then it's all paid for, and no house payment. So we basically only have living expenses and property taxes. I thought I would buy a bunch more car parts after retirement, but not really. I might find a trinket or two here and there, but what I need, I pretty much already have. I keep thinking well, maybe if one of us, or God forbid both of us, get all fugged up and have to live in a nursing home one of these days, we'll need money for that, but I just don't know.
Now I know why some of these old farts, er, OLDER farts buy new Corvettes and putt them around. Because you gotta do something with it.
