If you have a hemoglobin variant, such as sickle cell hemoglobin (hemoglobin S), you will have a decreased amount of hemoglobin A. This may limit the usefulness of the A1c test in monitoring your diabetes. If you have anemia, hemolysis, or heavy bleeding, your test results may be falsely low.
Who was the president that believed that a US-controlled canal across Central America was a vital strategic interest to America and so was largely responsible for construction of the Panama Canal? Theodore Roosevelt

The narrow land bridge between North and South America houses the Panama Canal, a water passage between the Atlantic and Pacific Oceans. The earliest Central American European colonists recognized this potential, and several proposals for such a canal were made.
