What was the life expectancy of soldiers living in the trenches?

The life expectancy of soldiers living in the trenches during World War I varied significantly based on factors like location and time, but on average, it was often just a few months, particularly for those engaged in intense fighting. Many soldiers faced not only the dangers of enemy fire but also harsh living conditions, disease, and malnutrition, which contributed to high casualty rates. Some estimates suggested that in certain battles, such as the Battle of the Somme, a soldier could expect to survive only a few weeks. Overall, the treacherous environment and relentless warfare severely impacted soldiers' lifespans.
