Working on my Resume

I have had a very interesting series of work experiences over the years, I have been employed, self employed, and unemployed, but never fired. Now, at 55, I feel that I am unemployable, so have decided to update my resume. The trouble is, I used to have one, but lost the file. Now I have been trying to re-write it in a new way, by using a blog. (no surprise there)
Surprisingly, most of it still remains in my memory. The ongoing attempt to update my resume is here.
