The patient is enduring the pain of the illness.

This festival is held every year.

The doctor diagnosed my symptoms.

The doctor diagnosed his illness.

My father is a doctor.

I am planning to have a physical examination next week.

He was known as a quack doctor in that town.

Even though he is a doctor, he doesn't take care of his own health. It's truly a case of 'physician, heal thyself'.

He admitted that it is difficult to execute the plan, saying 'it is easier said than done.'

Well then, I'm off.
