There's a question that's always puzzled me. The mystery is, how do horses eat food from nosebags?
I can see that, if the food is at just the right level in the bag, Harry the horse can eat and breathe at the same time. But, if you look at the geometry of a horse's head, its nostrils are at about the same level as its mouth. So, if the food in the nosebag is at the level that the horse can reach it with his lips and tongue, then he can't breathe. Equally, if Harry can breathe, he can't eat.
So, what does Harry actually do? Does he blow out through his nose at the same time as he breathes in through his mouth? Possible, but how does he know to do that?
Or, is it that when the chap starts tying the nosebag on, Harry takes a great gulp of air, and then very quickly munches his way down through the pile of oats in the nosebag, until he can take another breath? If not that, then what?
Of course, feeding horses from nosebags has become less prominent recently, what with the invention of the internal combustion engine and the advent of motor transport. But still, if you have the answer for me, I will be forever in your debt.
