It is not "just one hour" and "you get used to it in a couple of days". Apparently it takes weeks for the circadian system to adjust, and in some people it never does. In this day and age of around-the-clock life, global communications, telecommuting, etc., the clock-shifting twice a year has outlived its usefulness and should go the way of the dodo. The research also shows why studies of <A title="" target="_blank" href="http://scienceblogs.com/clock/fastsearch?order=date&IncludeBlogs=49&search=photoperiodism">photoperiodism</A> is not some arcane field, but has real-world applications.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;"> </td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/1575137E-F21C-4AE1-AADF-F54897C68393/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
