One's Life, Human Life, Life
noun
The kanji for person and life combined makes you think about human life. What is your human life like?
じんせい
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 人 and 生 both have two on'yomi readings, here's a mnemonic to help you: Your life boils down to just two things: jeans and a saber (じんせい). Your whole life, that's all you've ever needed, jeans and a saber. What are you, some kind of American pirate?
人生ってすばらしい。
Life is wonderful.
人生のパートナーになってくれませんか？
Would you be my partner for life?
人生はバナナのようなものさ。どれだけながいのかだれもしらないのさ。
Life is like a banana, you never know how long it will be.
