The expression “It takes more muscles to frown than to smile” if that is true, why do we seem to frown more than smile, considering it takes fewer muscles to smile?
In: Biology
Because it takes less energy to frown because the muscles aren’t contracting. The energy expended in contracting your cheek muscles is greater than the energy of those muscles at rest. For an example, consider your average fresh corpse. Very few smiles because there is no way to maintain the energy expenditure to keep the cheek muscles contracting to pull the lips and cheeks into a smile.
