According to a famous quote by Victor Hugo, the youth of old age is fifty.
Here's a breakdown based on the provided reference:
- The Quote: Victor Hugo is credited with saying, "Forty is the old age of youth; fifty the youth of old age." This quote is the foundation of the answer.
- Interpretation: Hugo suggests a perspective shift where one's perception of age changes. Forty marks the end of youth in some ways, but fifty represents a re-emergence or rediscovery of youthful qualities even as one enters old age.
Therefore, based on Victor Hugo's saying, the "youth of old age" is considered to be fifty.
