premise: My husband is a carpenter and he is in jeans all day sweating and building stuff . He has only been doing this since March and over the course of the months his legs have been getting these awful pimples . It has come to a point where they itch like crazy and of course turn into open sores because he is scratching . He had a similar problem when he was in the Army but it was never this bad . What 's a possible reason the writer 's husband is a carpenter ?
hypothesis: Because his legs have awful pimples .
