I need to unlearn some stuff

I have been doing a lot of translation lately covering all sort of subjects, from the Kalahari deserts to the manufacturing of electronic microchips, subjects I have no interest whatsoever in learning, not now not in a million years, but I ended up knowing so much (more than anyone should) and having a lot to say if ever asked about the reproductive system and behavior of the Mopane worms and everything there is to know about General Motors and its Chevrolet cars, that I wish to unlearn all of that.
