Ryuichiro is my best friend.

He was able to escape from the situation of forced labor.

He is working hard to support his family.

The labor market situation is tough.

He is known as an expert in gerontology.

He was diagnosed with tabes dorsalis.

Let's play the Werewolf game with friends tonight.

My grandfather is interested in gerontology.

Many workers are working in this factory.

My grandmother lives in a nursing home.
