We must prepare for life to 100 years from now.
Over the past five years, life expectancy for Koreans has nearly doubled and is projected to exceed 10,000 by 2030.
Reflecting this, the life expectancy of the majority of Koreans born today is over 107 years, and those currently under 50 are very likely to live to be over 100.
These statistics suggest that living to 100 is not just a problem for older people, but something that younger generations should also prepare for now.
This requires questioning traditional ways of working and living, and being willing to embrace change throughout life.
Planning for a 100-year life isn't just about financial matters or preparing for retirement; it means redesigning your entire life.
The two authors of this book prove this with analysis and insights from economics and psychology.

The three-stage life cycle of "education, work, and retirement" is collapsing.
As life expectancy grows longer and the choices of lifestyle and life paths diversify, the traditional three-stage life cycle of 'education-work-retirement' has begun to break down.
It is no longer possible to follow the same life decisions that were made by previous generations.
As a concrete example, we present a 100-year life scenario for fictional characters Jack, Jimmy, and Jane.
Born in 1945, Jack lived a traditional three-stage life.
I saved 4.3% of my income each year during my 42 years of work, and I had no trouble living off my pension for eight years after retirement.
For Jimmy, who was born in 1971, working 44 years would give him 20 years to retire.
To receive 50% of your pre-retirement income as a pension during your retirement, you would need to save 17% of your income every year while working.
Jane, born in 1998, has been retired for 35 years, so she has had to consistently save a whopping 25% of her income.
It is impossible to ask someone who lives to be over 100 years old to live a three-stage life and retire at 65.

Live a multi-stage life that utilizes rest and transition periods.
When you live to be 100 years old, you gain a lot more time than before.
How will you distribute your newfound time?
Breaking free from the constraints of a three-stage life presents a genuine opportunity to live more flexibly and proactively.
That's a multi-stage life with diverse careers and periods of rest and transition.
In the future, a multi-stage life will be established, with people engaging in two or three different careers and at some stage retraining to acquire new skills.
As life's stages increase, so do the transition periods between them, which are crucial in a longer life.
In "100 Year Life," various multi-stage life scenarios are analyzed and organized into concrete examples that are easy to understand, such as the 3.5/4.0/5.0 stage scenarios that extend the traditional three-stage life, and the portfolio life of old age where various occupations are performed simultaneously.

There must be a balance between tangible and intangible assets.
To cope with the coming changes and make the most of the transition period, the role of intangible assets, as well as tangible assets, is crucial.
We live with the perception that problems with tangible assets, such as real estate and deposits, must be solved, but we tend not to do the same for intangible assets.
For example, intangible assets such as productive assets that increase productivity and earn more in the workplace, such as skills and knowledge; vital assets that provide physical and mental stability, such as positive family relationships or partnerships and good health; and transformational assets that play a crucial role in multi-level life, such as recognizing one's own identity and being open to new experiences, are often neglected because they do not have a physical presence and are difficult to measure in value.
But in a multi-level life, these intangible assets are the key to our longer economic lives and a more prosperous life.
The authors emphasize that achieving a balance of these assets is essential for a happy life.

Traditional relationships, such as family, friends, partnerships, and gender roles, are changing.
As life gets longer and has more stages, the forms of life also change in various ways.
Families may have fewer children, but they may have to support not only their parents but also their grandparents.
As people increasingly work into their 70s or 80s, and as the majority of family members work, the traditional roles of men and women in the home are breaking down.
These changes have positive consequences, reducing the gap between men and women in society.
As a result, gender discrimination in society disappears as roles are naturally exchanged, such as taking turns as the main source of income depending on the stage of life.
Moreover, in a multi-stage life where age does not imply each stage, there are more opportunities to share similar experiences with people of different ages, and age discrimination also disappears.

Individuals, businesses, and nations must prepare for the future together.
Making a difference in life at age 100 depends largely on individual will and preparation, but the role of government and corporate educational institutions is also crucial.
Just as individuals redesign their lives, government policies and institutions, including laws, taxes, welfare, employment, and education, must be redesigned.
Companies need to recognize the transitional phase of their workforce and make efforts to support the development of intangible assets as well as tangible ones.
As life stages increase, the need for flexible work becomes more apparent, and the relationship between companies and workers is reorganized to accommodate diverse lifestyles.
As a result, the problem of age discrimination in the labor market may also disappear.
In this way, governments and businesses must adapt policies and regulations based on the three-stage life cycle to reflect reality.
"Life to 100" emphasizes that the reality we face is a challenge that must be addressed not only as individuals, but also by businesses and the nation.
