That's a rather weak analogy. I know a carpenter who builds furniture for his house in his spare time, a graphic artist that expands his portfolio on his spare time, and a cook that, uhm, well, cooks in his spare time. All of them are creators and builders of sorts. Although I would agree with you that some would prefer young ones without responsibilities and a lot of spare time over those with more experience but with families. I guess this reflects more of a certain company hiring philosophy more than anything else. Energy to the young, wisdom to the seniors.
