Watch cardiologist run with racers he saved on National Doctors' Day

The average American visits a doctor four times a year. Of course, if you’re suffering from a chronic illness or long-term disease, you may well see a physician more often.

In the U.S., most of us can take it for granted that when we’re unwell, need a vaccine, or just want a checkup, someone from the medical profession will be there to help.

However, on March 30 each year, we have the chance to highlight our appreciation by celebrating the work of physicians on National Doctors’ Day.

National Doctors’ Day dates back to 1933, when Eudora Brown Almond, the wife of Georgia physician Dr. Charles B. Almond, came up with the idea of giving doctors more public recognition. Locals were encouraged to send cards and lay flowers on the graves of doctors. From that, National Doctors’ Day was born.

Nowadays, the day is observed by healthcare organizations and medical institutions nationwide. Doctors are celebrated in a variety of ways, including receiving cards, gifts, and even red carnations from patients and colleagues, symbolizing the importance of the job.

March 30 was chosen to coincide with the first use of anesthesia, but the day is about appreciating doctors in all branches of medicine for their skill, dedication, sacrifice, and compassion in one of the world’s most essential professions.
