What can I do about flatulence? I'm 73.

Two main causes. The two main causes to flatulence is 1) air swallowed during eating, and 2) gas formed in the intestine. For #1, no talking during eating, small bites and chew your food well. For #2, avoidance of foods that tend to form gas (beans, certain vegetables, etc.) and avoidance of milk & milk sugars (cheese, ice cream, etc.) in those who are lactose intolerant. Talk with your doctor for more specifics.
