Not so surprising that many on GN are not keen on watching sport, and yes, many have suffered from DH being glued to the telly watching it in all its forms. That obviously doesn't reflect the general trend nationally across all age groups, otherwise there wouldn't be as much blanket TV coverage as there is for so many events.
DH and I do have our favourites, which don't always coincide, but fortunately we have telly in more than just the one room, so all is well. He gets the "Big Telly" for 6 Nations and World Cup rugby, I get it for Wimbledon and any other of the big tennis tournaments. We both enjoy watching athletics, swimming, and skiing, so back in the same room then. As for football, cricket, motor sport and snooker, both of us would rather watch paint dry. It works for us. We were both fairly active participants in a variety of sports in our younger years, so that may explain our ongoing interest.
