IQ maintenance .
You speak of IQ as though it is inherited only and persists for life. Discuss ramifications of high IQ individual that squander it by not training and nurturing it. Many people are capable and use IQ to be successful until age 25 but then do not take care of self, feed mind, or use IQ to enrich themselves or anyone around them due to complacency or perhaps no more hoops to jump through after career is obtained. Particularly, boomers with seemingly high IQ have so little executive functioning left , they don’t participate and do not serve anyone. I guess I want you to discuss that it’s not enough , you must maintain and contribute.
