Men at work.

Gardening is a profession for some and a hobby for others.. I don't know how much is this liked as a profession, but if it is liked, then it naturally becomes a hobby. There are farmers that make their living, while working all day under extreme weather conditons. And it can at times become a very tough job.
Then there are people who inculcate gardening as a hobby, and for them it is a wonderful feeling, since it then involoves primarily aesthetics.
