Prepare To Live A Longer Life: The Practical Implications Of Living Past 100

Longer Life

If you knew you were going to live 100 years, would you start to change the way that you live your life? In the past, living past 80 or 90 was rare, but with improved medicine and living conditions in many areas of the world, living to a hundred is becoming more of a reality.

This opens up opportunities for us to grow and experience more over a longer period of time.

Therefore, it’s important now more than ever to plan and prepare for life after retirement if you want to enjoy it in its entirety.

From understanding how pension plans are impacted by longer living to getting ready for technological advances that could alter the way people work, this book can help readers become better equipped for stepping into their centenarian years.

You’ll also find out why it’s necessary to answer the “big five questions” so that when you reach 100-years-old you are prepared and have plans set in place; allowing you make the most out of every moment without worry.

Really nothing should stop us from preparing ourselves now for a future full of extra years – we should all be ready for this upcoming ‘100-year’ life!

The Substantial Increase In Life Expectancy Is Thanks To Advances In Science And Education

Medical breakthroughs have revolutionized the way we live today, allowing us to enjoy significantly longer lifespans than previous generations.

Thanks to improvements in vaccinations, general hygiene and other medical advances, many childhood diseases such as smallpox have been mostly eradicated.

In addition, society at large now knows much more about nutrition and proper healthcare.

This is making children healthier and leading to longer lives -a child born in 1914 had a one percent chance of living to 100, but a child born in 2014 has a fifty percent chance of living that long!

Middle age is the second life stage, and here too we are seeing breakthroughs in how different illnesses are treated thanks to more sophisticated diagnostic technology.

On top of this, new research pointed out ways that people could further improve their health through better education on smoking risks and public campaigns addressing these risks.

Finally, the third life stage –old age– is also benefitting from medical innovations when it comes to diseases like Alzheimer’s.

With diligent research into these ailments combined with improved nutrition, advanced medical equipment and better sanitation; elderly patients are living longer and healthier lives too -In 1950 a 90-year-old man living in England had 30% chance of dying within a year; but this estimate is now 20%!

Increasing Life Expectancy Puts Retirement At Risk

The question of how increasing life expectancy is going to affect us has been a hot topic for many years now.

The traditional three-stage career model – finish school, work and then retire – is becoming obsolete and no longer able to sustain our lifestyle in retirement.

Take the example of Jack and Jane: though Jack only lived until age 70, his pension provisions were sufficient to help him enjoy a comfortable retirement.

But if Jack had lived to be 100, his pension would not have been enough.

Similarly, Jane will be living 30 years longer than Jack, yet her accumulated savings from active work versus future retirement years won’t come anywhere close to what Jack had – she’ll only have 1 year of active work covering 5 years of retirement.

It has become increasingly clear that rising life expectancy means standard pension schemes and old-age savings are no longer enough to ensure a secure financial future for most people.

While the older generation was able to rely on these methods for their retirement fund, it’s up to younger generations like Jane’s to make sure they save more money and plan more carefully in order to support themselves in the future.

Ai Will Replace Many Routine Jobs, But Humans Still Have An Edge In Creativity And Interpersonal Skills


The effects of artificial intelligence (AI) on the workplace cannot be understated.

AI is revolutionizing how work is done,Automating a range of tasks – from manual and cognitive to even complex processes – that used to be performed largely by humans.

For example, at Amazon’s warehouse, robots have taken over most inventory-related duties.

This is because these processes follow strict rules and don’t require people to make decisions.

However, there are still some instances where machines can’t quite replicate the unique capabilities of human workers, such as their ability to solve complex problems or create innovative ideas.

Take the popular iPhone, for example, which while it’s assembled by Chinese company Foxconn at a cost of only five to seven percent of its purchase price – it’s Apple’s engineers that design the product from which millions are sold who really generate value from this product – creating 640K worth of value compared to one worker at Foxconn creating 2K.

Humans also possess capabilities machines do not when it comes to interpersonal interaction and social perception – two areas in which people tend to thrive at and enjoy engaging in with other people.

So although AI might take over some jobs currently performed by human beings, it won’t replace them entirely anytime soon due to certain skillsets that computers simply cannot reproduce yet.

It’S Time To Make Lifestyle Choices That Affect Your Overall Health And Wellbeing

In today’s age of longer life expectancies, it is becoming increasingly important to take care of ourselves.

Taking the time to be physically active and making healthy lifestyle choices can help us address not only the issues of aging bodies, but also those of mental decline.

When we are faced with decisions, having knowledge about our own strengths, weaknesses and values can help us make the best decisions for ourselves.

Ultimately, this will help us deal with change more productively in later stages of life.

Intangible assets like health and self-knowledge are also becoming more valuable.

Understanding oneself better can help guide our decisions and point us towards a path that is best suited for our well-being.

As such, investing in these intangible assets is essential in preparing for a 100-year life.

Embracing Exploration To Achieve A Fulfilled Life

As life spans increase, allowing for phases of exploration is becoming more important than ever.

The traditional paths of schooling, work, and retirement don’t apply so much anymore in our current working world, leaving a lot more room for young people to explore all the options available to them.

It’s essential to take advantage of this freedom and explore, in both work and life, all possibilities that could be beneficial to you.

Doing this during times of natural life transition – between 18 and 30 years old, mid-40s, 70s or 80s – can have a greater impact on your future years.

Exploration doesn’t always mean travelling through other countries; it can also include creating something independently or setting up an alternative income source such as starting a blog and selling an online course.

As we learn by doing things like these we gain credentials that may come in handy one day.

Ultimately, exploration offers us freedom from the “normal” working life by emphasizing process over money and financial assets.

That’s what makes it so especially valuable today with our increasing lifespans.

Understanding Your Finances And Increasing Financial Literacy Is Key To Planning For Retirement


A comfortable retirement is not just about having enough money.

It’s also about planning and understanding your finances.

Knowing how much of your current salary you need to live comfortably in retirement, and how to manage inflation, are key aspects for a secure financial future.

At the same time, financial literacy is crucial for smart financial planning.

To help with that, the Big 5 Questions test will assist you in developing better financial literacy.

This involves questions such as how interest and inflation rate affect savings over time, as well as basics regarding stock investments and mortgages.

Once you can answer these questions correctly, it will provide you with a better understanding of investing, saving and budgeting – all of which are necessary for successful retirement planning.

With these tools in hand and an improved knowledge, you’ll be able to achieve the security and comfort that comes with a successful retirement plan!

Discovering Your True Identity Helps To Shape A Meaningful Life In The Modern World

If you want to make the most out of your life, it’s essential to first understand who you are.

Historically, societal expectations and traditional gender roles helped define a person’s identity, but that’s no longer the case.

As civilization evolves, there is now much more freedom to shape our lives based on our own values and ambitions – but only if we know ourselves well enough to do so.

Without knowing your true self, you won’t be able to develop plans that work for you – whether they deal with finances, personal knowledge or social networks.

Experimentation in daily life is key in order to figure out what works for you and what doesn’t in order to create an individualized lifestyle trajectory catered specifically towards your needs.

The great thing about living longer is that it gives us more time and opportunities to explore various options and discover our true identity – as opposed to just relying on traditional roles or familial circumstances.

By understanding yourself and cultivating plans that fit your values over time, you’ll be able to get the absolute most out of your 100-year life!

Wrap Up

The final summary of The 100-Year Life is that living longer offers new opportunities to individuals, but it also poses challenges for society as traditional roles such as schooling, work and retirement become less relevant.

To tackle these challenges, one should build regenerative friendships.

These are the kind of friendships which support us intellectually, emotionally, and spiritually; they are much more than just professional connections.

Through these relationships, a person will find themselves mentally and creatively stimulated in a multitude of ways, which helps to bring a sense of vitality into their life.

Ultimately, this book encourages us to invest time, energy and feeling into our regenerative friendships – something we can all benefit from!
