Final Answer:
The specific information regarding the individual lifespans of real cowboys around the year 1890, as studied in Connie Brooks' book "The Last Cowboys," is not provided in the given context.
Step-by-step explanation:
In "The Last Cowboys" by Connie Brooks, the focus is on a sociological study of cowboys in West Texas and Southeastern New Mexico around the year 1890. The book draws insights from a sample of 32 cowboys but does not offer detailed information about the specific lifespans of these individuals. Unfortunately, the dataset presented in the book does not include the years of longevity for each cowboy in the sample.
The absence of detailed lifespan data in the given context suggests that the primary emphasis of the study may be on broader sociological aspects such as lifestyle, working conditions, and community dynamics rather than individual lifespans. Historical studies often grapple with limitations in available data, and in this case, the focus may be on providing a comprehensive understanding of the cowboy experience in the late 19th century.
While the book contributes valuable sociological insights, including the challenges faced by cowboys during that period, it does not furnish specific information about the duration of individual lives. Therefore, to determine how long real cowboys lived based on the book, we must recognize the limitations of the provided information and acknowledge that the study may be more qualitative than quantitative in its approach.
