What is the old age (kibar) intended in Sharia, when does it begin, and is a father in his sixties or seventies considered old?

Allah Almighty commanded beneficence towards parents and honoring them, especially during the period of weakness and old age, as their need for care and kindness increases. The old age mentioned in the verses does not have a specific age, rather its criterion is weakness and the need for righteousness, kindness, and beneficence.
