<prompt> Human: Ill preface this by saying I currently have an emergency fund thats about 4 months of my current expenses, low 5 figures. I just cant think of any scenario where Ill need it. My employer has never had layoffs so I dont think there is any chance of job loss. I live in a condo thats very new so Im extremely unlikely to have any large home expenses in the next decade, at least not without lots and lots of warning so I can start saving. If my car dies tomorrow I could easily put 2000 or so down paid out of short-term savings and finance at a fairly low rate, then reduce retirement contributions until it is paid off or not, if the rate is really low.The only thing Im not sure of is what kind of medical expense could hit me out of nowhere. I have pretty good insurance, my deductible isnt large. What kind of thing could get me? What scenarios should I be worried about?Im probably going to keep the e-fund anyway because Im sure Im missing something, Im just curious if anyone can come up with anything Im missing. Maybe its obvious and I should have posted this Monday  <response>: You must have a very limited imagination. Or not read too much current events. Education could be upset by technology innovations. If you are attached to a public institution such as a school you could be affected by cuts in government budgets. If you are attached to a private institution, you could be affected by mergers or reorganizations or business slowdowns. You are always subject to natural disasters and possible illness, or people you care about are. No matter how well built your condo, there could be problems, or people who are responsible for fixing things could fail to perform, or even abscond with funds. Municipalities can make special assessments. Cars can need expensive repairs. There are lots of low-likelihood events which could occur and could be handled with ready cash.There are relatively few reasons to need thousands of dollars on a moments notice, but quite a few scenarios where ready access to a few months worth of expenses could make life much much easier - that is turn a situation from an emergency into a practical management problem.If you really are bulletproof, good for you, but I think you are not.
