I'm not interested in sport at all, most of it bores me stiff. Maybe with the exception of the Olympics, when Mo Farah does that thing he does where he's lying last and then overtakes all the others, that I find exciting and some of the other track events. My husband plays golf, loves talking about that, we've been together over 35 years and I've still no idea what he's talking about. He and our sons follow West Ham, one in particular will phone as sure as night follows day after a match to speak to his dad so they can analyze the whole boring 90 minutes or however long a match lasts. No idea why they care so much, if they lose it isn't tragic no one dies! I just zone out. My husband also has a reasonable interest in rugby and tennis, again don't give a whatever!
Talk away, perhaps make sure womens' toilets remain just that, so those like me can escape occasionally from such interminable boring topics. I defend their right to talk about it though. In the words of Pink Floyd "Hey Head of Chartered Management Institute, leave them men alone"
