Final answer:
Retirement maturity refers to being well prepared emotionally and financially to retire.
Step-by-step explanation:
The term "retirement maturity" is not a widely used or recognized concept in standard financial or retirement planning terminology. However, if you are referring to the maturity of retirement plans, it may involve the phase when individuals are actively transitioning into or living in retirement.
Retirement maturity refers to being well prepared emotionally and financially to retire. It means having a plan in place to support oneself during retirement years and being psychologically ready to transition into this new phase of life. Retirement maturity does not specifically pertain to living an active lifestyle or being a grandparent to grandchildren.
