My grandfather is interested in gerontology.

My grandmother participates in the local old people's club every week.

He is known as an expert in gerontology.

An old person was playing with his grandchild in the park.

My grandfather is being seen by a specialist in geriatric medicine.

Grandpa was scratching his back using a backscratcher.

I installed a new doghouse in my garden.

She is the mother of quintuplets.

Will the day ever come when I am freed from this eternal torment?
