In primitive societies life is a succession of stages. The needs and purposes of one stage having been fulfilled, there is no particular reluctance about passing on to the next stage.

A young man goes through the power process by becoming a hunter, hunting not for sport or for fulfillment but to get meat that is necessary for food […] This phase having been successfully passed through, the young man has no reluctance about settling down to the responsibilities of raising a family.

(In contrast, some modern people indefinitely postpone having children because they are too busy seeking some kind of “fulfillment.” We suggest that the fulfillment they need is adequate experience of the power process — with real goals instead of the artificial goals of surrogate activities.)

Again, having successfully raised his children, going through the power process by providing them with the physical necessities, the primitive man feels that his work is done and he is prepared to accept old age (if he survives that long) and death.

Many modern people, on the other hand, are disturbed by the prospect of physical deterioration and death, as is shown by the amount of effort they expend trying to maintain their physical condition, appearance and health. We argue that this is due to unfulfillment resulting from the fact that they have never put their physical powers to any practical use, have never gone through the power process using their bodies in a serious way.

It is not the primitive man, who has used his body daily for practical purposes, who fears the deterioration of age, but the modern man, who has never had a practical use for his body beyond walking from his car to his house. It is the man whose need for the power process has been satisfied during his life who is best prepared to accept the end of that life.
