Stay Sharp, You Old Bastard

I'm not that keen on getting old. But it seems you can't always get what you want.

I really, really want to stay sharp as I get older (and more feeble). But heads up you old bastards because some of you are not doing a great job of this! You'd better read on...

Because maintaining a sharp mind is not only possible, it’s within our control.

Today, I want to share some science-backed strategies to keep your brain in top shape, inspired by the story of Marie Jerusalem, a 62-year-old founder who has proven that age is just a number when it comes to mental agility.

Meet Marie Jerusalem: A Case Study in Cognitive Resilience

At 62, Marie Jerusalem is not only keeping up with the ever-changing demands of the corporate world, she’s thriving. Marie’s journey is a testament to the power of adaptability and lifelong learning. After being let go from her role as a chief people officer at aged 57, she could have retired. (She should perhaps have resigned in disgust at being given such a rubbish job title, but I digress...)

Instead, she launched Rocket50, a platform designed to help older workers navigate the job market. To do this, she had to learn new skills quickly—from AI integration to social media marketing.

Marie’s experience underscores a vital truth: staying mentally engaged and continually learning new skills can boost confidence and mental resilience at any age.

She believes that the demands of launching her business and engaging with others have strengthened her cognitive abilities.

The Science of Ageing and Mental Sharpness

Contrary to popular belief, aging doesn’t necessarily mean cognitive decline. Research from the National Institute on Ageing and Columbia University Irving Medical Center reveals that while there are some normal age-related changes in thinking speed and attention, decision-making and abstract reasoning skills may actually improve with age.

This is particularly good news as people aged 55 and older are expected to make up more than a quarter of the workforce over the next decade. Many are working past retirement age, driven by a desire to stay engaged or due to financial and caregiving responsibilities.

Regardless of the reason, one thing is clear: maintaining mental sharpness is a priority.

Key Habits for a Sharp Mind

1. Prioritise Quality Sleep

Sleep is a cornerstone of good health, particularly for the aging brain. Dr. Marie-Pierre St-Onge from the CUIMC Center of Excellence for Sleep & Circadian Research highlights that sleep disturbances are linked to cognitive impairment.

Aim for seven to nine hours of sleep per night, stick to a regular sleep schedule, and develop a calming bedtime routine to improve sleep quality.

And no, that doesn't include the time spent asleep in front of the TV at 5pm watching Pointless. You know who you are.

2. Stay Physically Active

Exercise is crucial for brain health. It helps counteract age-related shrinkage of the hippocampus, which is vital for memory.

Even moderate activity, like 10 minutes of brisk walking or biking daily, can enhance mental processing and task efficiency. Plus, regular exercise can alleviate sleep problems like insomnia.

3. Maintain Social Connections

Strong social ties are essential for mental health. Engaging with friends, family, and colleagues keeps the brain stimulated and protects against cognitive decline and dementia.

I'm loathe to include this point, lest my parents use it as an excuse to visit more often but it's also been shown that socialising across generations can introduce new perspectives and invigorate the mind.

4. Embrace Lifelong Learning

Continuous learning keeps the brain developing. Activities that require focused attention, such as learning a new language or musical instrument, strengthen executive functioning and emotional regulation.

Even enjoying the arts can boost cognitive health. The field of neuroaesthetics suggests that engaging with music, dance, and visual arts can improve attention and extend lifespan.

That's great news, so if any of you want to engage with my techno music on Spotify, just let me know. It will extend your life. Probably.

Positive Mindset and Ageing

A positive outlook on ageing can significantly impact your health. Research from Harvard T.H. Chan School of Public Health indicates that people who view ageing positively live longer and have better physical and cognitive health.

Embracing the wisdom and self-acceptance that come with age can lead to a more fulfilling life.

Overcoming Stereotypes and Staying Engaged

It’s time to retire outdated stereotypes about ageing. Lesley Steinman from the University of Washington emphasises the importance of active participation in ageing. Older adults have many opportunities to stay engaged and improve their quality of life, despite systemic challenges.

Positive thinking can also alleviate mental health issues like depression, which is crucial for maintaining cognitive function.

Find Your Passion

Marie Jerusalem’s story is a powerful reminder to find your passion and stay engaged. She wakes up every day eager to learn and connect with others. Her advice? “Find your passion and stay engaged for as long as you can, because that’s what really makes you feel like you’re alive.”

Actionable Takeaways

Sleep Well: Aim for 7-9 hours of quality sleep per night.
Exercise Regularly: Incorporate at least 10 minutes of moderate activity into your daily routine.
Stay Social: Make time for friends and family, and seek out new social connections.
Keep Learning: Challenge your brain with new skills and hobbies.
Think Positively: Embrace the positives of aging and maintain a hopeful outlook.

Maintaining a sharp mind as you age is a continuous journey. By integrating these strategies into your daily life, you can enhance your cognitive health and enjoy the many benefits of a vibrant, engaged mind.

Until next time, stay sharp.
