>>864372In the real world sense heck no. I'm fucked without my meds now
I have 25 years experience when it comes to /out/ and a solid professional background in engineering. despite this in the past 5 years I've become heavily dependant on medication to remain functional, and am realistically 2/10 as fit and able as I was 6 years ago.
I've got the know how for allsorts of stuff, but I wouldn't really be able to use it.I can get some things done, and/or instruct others how to do stuff but I'm pretty screwed alone.
Long term plan is be to dig in where live. 
My wife and I try to maintain a month in hand food/supplies (inc domestic fuel) wise for us and the cats ( we have 2 indoor cats) I have over that past few years staggered my prescriptions to the point where I'm 4 months ahead and rotate old for new. We are by no means part of the crazy prepper movement (I fucking hate the term) but we are 'careful' and like to plan ahead a bit 
We've already discussed and planned how to board up the windows from the internal doors around the house and make things as secure as possible within our community. If it did get real sketchy that we have to leave ( we live about 15 miles down the coast from a nuclear power station about to be decommissioned, and a new one is looking at being built to replace it), we each have a 'trouble kit' packed and ready to go along with a stocked cat carrier for the moggies.
Because of where I live I could probably get away with poaching livestock food wise in the short term as the most sensible and labour easy ( sheep are dumb fuckers) option and seafood (I live 150m from the coast) is also readily available. My biggest problem is fresh water. If the mains lose pressure the closest fresh water source that isn't in the middle of the local town is well over a mile and a half away, and building a desalination plat (an evap) isn't practical due to the fuel needs :/
