What effect did industrialization have on life expectancy in the united states and western europe?

The effect that industrialization had on United states and Western Europe was improvement in weapons and their miliatry.

I think that life expectancy went up about 30 years

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
