Nessa Careyの 'Junk DNA' を読んでいます。
It's relatively easy to take a biopsy, for example from skin, and isolate the fibroblasts. These will grow and divide in culture. What the researchers discovered all those years ago was that the cells wouldn't keep dividing forever. There came a point when they stopped dividing, even when supplied with all the nutrients and oxygen they needed. The cells didn't die, they just stopped proliferating. This is known as senescence.

Senescence is a fancy way to describe the process of aging. If you don’t want to admit straight out that old age made you lose that tango contest, blame it on senescence — it sounds mysterious and exciting. Senescence is sometimes used in a scientific context to describe cells in your body that can no longer grow and divide, which can affect your ability to dance like you did when you were 20.
まさに私はこの状態に近いのですが、英語では "old age" とは言わず、 "senescence" とか "senescent"(形容詞)を使った方が 'it sounds mysterious and exciting' なのですね！ 日本語にもそんな表現があるといいですね。
