People have learned to do two things at once ! eg. I listen to videos and do my yoga at the same time. It depends on how much visual input is required . In the case of your videos it is listening skills ( could equally be a podcast but I like seeing the person behind the voice) . That bit of French towards the beginning was good ! And yes I understood. You are an interesting character; ie you have a lot of interesting points to make and to me you come off as a quintessentially British gentleman with your wonderful English accent and the manner of speaking lol !
