In what may be his final book, Ray explores death, dying, and how one should not stop living even when given a short time to live. Ray also shows the value of a "time portfolio" of hobbies that can offer both a cure for boredom and potential profit. Since his 2021 diagnosis of end-stage liver disease, when he was told he might not even survive the year, Ray has accomplished more than in almost any other three-year period of his life. If you're obsessed with your nest egg, which might be wiped out in old age with illness, and want a fresh perspective on retirement planning that does not put money above all else, this is the book for you. Ray also includes, as an appendix, his entire tunnel book which purports to solve chess, or at least the opening. The entire tunnel was conceived, and that book written, long after Ray was diagnosed. We will all face the same challenges as Ray; this is his blueprint for dealing with this inevitability.
