The older and more experienced you get, the harder it is to assume others who will have to deal with the code will have "similar knowledge".

"However, I don't think you need to make everything readable by a junior level coder." I may not be a junior-level coder, but I may still be 'jr' with your particular language or framework, but have been assigned your code because you've moved on to something else.
