Henderson's argument is that how one grows old and faces death reflectsthe choices one has made about one's life. The deep "self-exploration"which age forces upon us is what's so frightening about it. As Hendersonputs it, "when we are old, we are more ourselves than we have ever beenbefore," meaning that it can be difficult and painful to think honestlyabout our lives, let alone change them. This rich book will be welcomed bysenior citizens. It might even be of interest to the young, for itsfearless invocation to "know thyself" is an inspiration--and a challenge--at any age.
