Engaging with people over 70 outside your family offers unfiltered wisdom on life's biggest regrets. This perspective is a powerful tool for re-prioritizing your own life to avoid making similar mistakes, especially concerning career and relationship choices.

Seemingly harmless jokes and dismissive attitudes about aging are not benign. The World Health Organization found that older adults with negative self-perceptions about their own aging live, on average, 7.5 years less than those with positive views, making the psychological impact of ageism a significant public health hazard.

Rigorous studies show one's mindset about aging is a better predictor of longevity than key health indicators like cholesterol, blood pressure, or even smoking. People with positive views on getting older live, on average, 7.5 years longer than those with negative views—a greater impact than that of consistent exercise.

To improve overall enjoyment and wisdom, focus your time on three sources: dogs for unconditional love and loyalty, kids for childlike wonder and presence, and 'dead people' (i.e., great authors and thinkers of the past) for deep, time-tested knowledge over the ephemeral noise of social media.

Jane Fonda argues that mortality gives life its meaning and creative spark. At age 60, she consciously began to live in a way that would minimize future regrets. This focus on the end-of-life experience, rather than fearing it, informs present-day actions and creates a more purposeful existence.

End-of-life regrets often stem from things left undone or unsaid. To avoid this, one can regularly use a simple 'final checklist'—a set of powerful questions about one's life, relationships, and priorities. This isn't about cleaning up at the end, but about actively building a life so full that there's nothing left to fix.

To make better long-term decisions, annually ask what you will respect in 5-10 years across key life domains (work, family, health). This forward-looking self-judgment, inspired by his parents' end-of-life reflections, creates clarity and urgency to act now, rather than in the "ninth inning" of life.

The shocking realization that, based on age and visit frequency, you may only see your parents a handful more times can be a profound catalyst. This stark calculation of remaining time often prompts significant life changes, such as relocating, to prioritize and maximize crucial family connections before it's too late.

As children become independent adults, showing vulnerability and asking for parental comfort is a profound gift. This act reaffirms a parent's purpose and sense of value in a way that material success cannot, strengthening the family bond across generations.
