Am I wrong in thinking that technology amplifies how we gauge the energy required for physical activity? With just a few moves of my finger I can watch a video, read a paper, talk to people, etc. Contrast that with running, lifting, etc. The effort required for the comparatively minute results we achieve seem dramatic across this contrast. I wonder if having computers with an internet connection in their pocket at all times is making kids lazy... which may be an additional factor in this reported situation.
