I agree. As far as fluorescent lights are concerned, I noticed that after spending only ONE hour in a room without windows (like in a basement), and with fluorescent lights, I feel VERY tired. One cannot stress enough the importance of natural light and natural air. Just spending a few minutes outside, in the sun, has a relaxing and energizing effect for me. > I think this kind of environment is much more > exhausting than hard physical work in the outdoors. (That's my > opinion, anyway). Yes, but it's a different kind of exhaustion (perhaps more nervous than muscular?). --Jean-Louis Tu <[log in to unmask]>
