 Another good one is if you didn't have a big emergency fund in retirement, that's probably a problem. I mean, you want to have a lot of cash on hand. Yeah, explain cash on hand and what that might even look like. How much? Yeah, I mean, there's plenty of rules of thumb and calculators out there. Three to six months of expenses is thrown around a lot. But I would just say that any amount of money to have in cash is probably appropriate so that it would cover any big expenditures. A roof goes out, you need a new water heater, the kid's in jail, something crazy goes on.
