I think so too.I remember some years ago reading about PH saying something about his eyesight no longer being well suited for hunting. - Probably hunting birds in particular, which requires that you are able to focus while moving your eyes rapidly.
Thank you Muhler for posting this photo of the Prince consort and his hunting buddies who, I believe, enjoy the hunting lunches more than the actual hunt! Here is your cue, please, tell us about Danish hunting food! In return (and in thanks for the footman joke, that was very good indeed!) I give you this link to the recent photo of a Canadian 'bird' that would cause any man to focus and move his eyes rapidy!
