Introduction
The age of 60 is not "the beginning of the end." It is the entrance to "the best free time."
Chapter 1: Why am I so anxious? — Exposing the unknown shadow
1 The true nature of the "fear" you hold
2 "Where did I go wrong in my life?" Nights trembling while staring at the ceiling
3 The most terrifying scenario brought about by the thought paralysis of "it'll work out somehow"
4 Reality in numbers: In 2050, one in two households in Japan will be "single"
5 The magic notebook that "visualizes" anxiety: Writing alone calms the brain's panic
6 Breaking the curse of "do it yourself." Independence means "increasing your sources of support."
Chapter 2: The art of transforming financial despair into "hope" — Rebuilding "earning, protecting, and growing"
1 "I'm scared of living long"... Nights weighing bank balance against remaining lifespan
2 Saving and frugal living alone are dangerous signals!
3 The way to eliminate financial anxiety is to diversify your "sources of reliance"
4 Pensions are not "savings." Receiving strategy as "longevity insurance"
5 No need to work until death. "Loosely and long" multiple income streams strategy
6 Is "investment scary" true?
[Column]: What you need to know about "new NISA limits"
7 Money is not "the goal" but "a ticket." Where do you want to go?
Chapter 3: Overwriting the fear of lonely death with "loose connections"
1 On holidays, "Oh? Haven't I talked to anyone today?"
2 Have a "third place" beyond family and work.
Horizontal connections without vested interests are the strongest safety net
3 Is the longed-for "sharing a house with friends" possible?
—The reality that's not like a drama and the recommendation for "living nearby"
4 Human relationships from the 50s onwards are 90% "letting go."
Specific steps to declutter obligatory relationships and find a new "place"
5 Loneliness is not "sadness" but another name for "freedom." How to make the most of "solo living" from your 50s
Chapter 4: Cherishing body and brain like "antique dolls"
1 Afraid to look in the mirror. "I'm not young anymore" — that resignation is actually the biggest aging factor.
2 Overreliance on health information. What's more important than spending money on expensive supplements
3 Intellectual curiosity is the strongest anti-aging. "Adult re-learning" not for earning money
4 To avoid needing caregiving. 10-minute walk a day and your personal "mood-boosting list"
5 How to find a lifelong hobby that lets you say, "Today is the youngest I'll ever be," even at 80
Chapter 5: Protecting the last fortress — The defense line of "caregiving, housing, and preparation"
1 Parental caregiving and spousal bereavement. The mountain of procedures forced upon you amidst "loss"
2 Bank accounts are routinely "frozen immediately after death." Don't expect rural benevolence; make the system your ally.
[Column] "Ending Note" is a love letter to those left behind
3 "I have to do it" is the gateway to mutual collapse for parent and child. The skill of thoroughly utilizing professionals (care managers)
4 "Owning a home" might not be a gift to your children but a "shackle."
Relocation and downsizing from your 50s
[Column] "Tomb closure" is the ultimate love. The choice not to leave an "invisible burden" to the next generation
5 Protecting the solo dweller's death. Fearing "lonely death"
"Whether married or single, everyone will eventually become a solo dweller—"
