Since I used the later years of my academic career to dive into the mysterious world of process control. I understand you perfectly. For each year, fewer and fewer people could get the jokes. General chemistry jokes will hit home with almost all my university friends, but I think I know less than 20 people who will get the process control jokes.

That certainly does not help. I've more or less resigned myself to relegation now.I guess QPR losing to Bolton does not help ...
