Wouldn't it be easier to just adjust our activities rather than messing with all our clock's and watches...I asked this once to a write in show and was told there was allot I wasn't considering but then they didn't offer any examples. Can anyone explain this to me? Why not just go into work an hour earlier and quit having to keep resetting all many devices?
