"Chapters in this book give us crucial insights into the impact of military service, including the surprising finding that service can serve as a protective factor in some contexts, throughout the aging process. Topic areas include the effects of combat and stress on longevity and brain functioning; the use of memory, cognition, and ego development at various points in life; the relationship between experiences of discrimination and the later development of PTSD; marriage longevity; employment; and the way notions of patriotism and nationalism among service personnel and their families may change over time."
