Why not. Groundskeeper (manual labor) at 50, when you could presumably start that job at 16. At 16, anything over 40 (visible signs of aging) is an ol’timer
Especially when you have a job that uses a lot of seasonal teenage labor. You end up with one group of employees who is "young" (16-early 20s) and works there in the summer, and one group that is "old" (25+) and works there year round.
