I'VE JUST INVENTED THE BLOBBOGRAPH
This is a new form of graphic communication, (or most probably it isn't), but these two examples of this sort of mutant Venn diagram show some of the differences between the roles in my life before I retired two years ago , and after.
BEFORE
AFTER
So it seems that there could be an analogy between the impact of retirement on my life and that of the internet and its associated technological innovations on the print media. Whereas as one element used to predominate now various differing ones compete and overlap in confusing way and believe me, I wish I knew how to monetise it!
