To work as a lumberjack, cutting down trees.
Wikipedia
A lumberjack is a worker in the logging industry who performs the initial harvesting and transport of trees for ultimate processing into forest products. The term usually refers to a bygone era (before 1945) when hand tools were used in harvesting trees principally from virgin forest. Because of its historical ties, the term lumberjack has become ingrained in popular culture through folklore, media, and spectator sports.
