I'll add one - I immediately ignore any job ad that contains anything along the lines of "Work in an exciting/agile fast-paced, dynamic environment", which pretty much signals that only youngsters need apply.
Of course, if the job really is chaotic and high-stress, then that signal should probably stay in the job ad.
