Although smoking does not always affect scores on smell-tests, it is widely believed to reduce sensitivity. A recent study at the University of Pennsylvania suggests that, contrary to popular belief, blind people do not necessarily have a keener sense of smell than sighted people.
In American cuisine, ribs usually refers to barbecue pork ribs, or sometimes beef ribs, which are served with various barbecue sauces. They are served as a rack of meat which diners customarily tear apart by hand, then eat the meat from the bone.
Cuts of meat differ from country to country. Beef, veal, lamb and pork are mostly cut into loin, rib, round, roast, shoulder and leg portions. Pork bellies, hams and bacon are also valued, as are sweetbreads, liver, kidneys, tripe, caul fat, tongue, heads, tails, feet, heart and brains.
