[00:00.00]M:I'm so tired I can't see straight.
[00:02.82]W:You're been tired a lot lately,haven't you?
[00:05.36]M:Well,for the last few weeks I've had to stay up most of the night to observe star configurations for a project for my astronomy class.
[00:12.46]It's awful,no matter what time I go to bed,I always wake up at six a.m.That's the time I usually get up.
[00:19.49]W:Your biological rhythms probably haven't adjusted to your new schedule.
[00:23.56]I've read that some people have a lot of trouble when their sleep rhythms are interrupted.
[00:28.19]Even sleeping don't help them.
[00:30.38]M:I know,in fact,I've heard that there're now several special treatment centers for sleep disorders across the country;
[00:37.64]some people sleep too little,some sleep too much,some walk in their sleep.
[00:42.58]W:I'd like to find out how they treat problems like that.Maybe you should go to one of those centers.
[00:47.60]M:Not me.After next week,my project will be finished and I'll go back to my regular hours.
[00:53.24]Now,I know for sure that I don't want to be an astronomer.
