They still have to do that in the dark no matter which leaps we make the clocks go. /BAH

On the <snip> What is wrong is forcing the entire populace to go through a jetlag twice a year. Their driving is more dangerous and productivity falls until each person has adjusted his/her internal time clock. Congress has been passing laws about truckers getting enough sleep. OTOH, they pass clock resetting laws which causes everybody to not get enough sleep. What's wrong is that it's dangerous and unhealthy. /BAH

The idiosyncratic pronunciation of "one" / wVn/ is supposed to be a dialectal intrusion, isn't it? I remember a passage in _Tom Brown's School Days_ about the name of a local feature called "the Blowing Stone" being pronounced the "blawing stwun"*. The pronoun would presumably not share that pronunciation if many people had not assimilated it to the number. > *Yes, here it is: http://en.wikipedia.org/wiki/Blowing_Stone

What's stopping people from going to bed an hour earlier that night? Anyway, that only works for one direction. The other time, everyone gets an extra hour of sleep, and therefore should be more rested and less likely to have accidents. -- Cheryl |
