Yesterday i had to have 6 teeth removed. While it does not seem like a major thing, it can really throw you around a bit, like the oral surgeon suggested the rest of the week off work which i did arrange, and could not drive for 48 hours after the anesthetic, or while taking the strong painkillers if they are needed.
While this has meant i needed to take leave from my normal job, as you can see from me posting here today it is not something that will stop me in my business. Having no fixed office means that i could be writing this post from anywhere, in bed, at my desk at home, or given i had the access and was in the situation from a hospital bed.
This is probably one of the benefits that you do not want to have to make use of with having no fixed office though, as i know i do not like being unwell, or being confined. However it does go to show that when you work with no fixed office, you really do have everything that you need to work at home, or wherever else you may be as long as you have your laptop, or an Internet connection.
