'Old' in the Bible

Nicodemus says to him, How can a man be born being old? can he enter a second time into the womb of his mother and be born?

Verily, verily, I say to thee, When thou wast young, thou girdedst thyself, and walkedst where thou desiredst; but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and bring thee where thou dost not desire.
