"Exercise and eat healthy food." We hear that all the time but it means different things to different people.
When Uncle Pervie plowed the corn in Sontag, or got the grass out of the peas with a hoe, he was getting aerobic exercise. When he ate peas and corn he was eating healthy food.
Most of us don't plow corn or hoe grass out of the peas. We have to get our exercise some other way. We can still get plenty of healthy food.
