I lurk on a homesteading board occasionally, and there are some people pretty worked up about the Ebola thing. One poster said that last year she did not leave her property from November to March-she had everything delivered-and plans to do the same this year.
Honestly, even if I had a lot of property I don't think I could go that long without leaving it. Supposing that your income remained same and everything you needed could be brought to you, how long could you go without leaving the dwelling you currently live in?
Over a year. - Seriously.
End of (October?) 2010-Sept 2011, I suffered from extreme social anxiety and aside from situations where I absolutely HAD to leave the apartment - I didn't. My doctor diagnosed me as having mild agoraphobia during that period of time and offered to put me on anti-depressants, but I refused them.
I did not begin leaving the house regularly until after my fiance moved in, which was December 2011. But then of course it was winter, so we didn't really go anywhere except to family Christmases.
My first trip back out into public would have been around April 2012... we went to a local park and I had an anxiety attack because of how many people were there. I slowly got better about public places, but it wasn't until January 2013 - when I received Toby - that I was outside every day again... I actually started to make friends again, and DO things on the weekends. I found myself again and started going for long walks on the nature paths behind the apartment. We took the kids out more often, did more things as a family...
This weekend, I've been invited to bring my dog to a Howl-oween party for dogs, and the following day we've been invited to the dog walk-a-thon for the Farley Foundation. I have volunteer jobs, interact regularly with people, but it took a lot of time to get *ME* back.
So yea - I could easily, go a year or longer without leaving - even now.
