My grandfather is suffering from Parkinson's disease.

He lost his temper after losing the game.

I get motion sickness as soon as I get on a boat.

I caught a cold, so I decided to take a sick leave.

My younger brother is a sick child, always under the care of a doctor.

He says 'sickness and health start with the mind,' and strives to have positive thoughts every day.

He needs special care because of his inherited disease.

He got infected with brucellosis because he was handling cows that were infected with the disease.

He used malingering to skip school.

My sick father is seen by a doctor every day.
