Getting less sleep has become a bad habit for most American kids. According to a

new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at

or later on school nights, even though they have to get up early. Last year the

Foundation reported that nearly 60% of 7-to 12-year-olds said they felt tired during the

day, and 15% said they had fallen asleep at school.

How much sleep you need depends a lot on your age. Babies need a lot of rest:

most of them sleep about 18 hours a day! Adults need about eight hours. For most

school-age children, ten hours is ideal. But the new National Sleep Foundation survey

found that 35% of 10-to 12-year-olds get only seven or eight hours. And guess what

almost half of the surveyed kids said they do before bedtime? Watch TV.

“More children are going to bed with TVs on, and there are more opportunities(机

会) to stay awake, with more homework, the Internet and the phone.” says Dr Mary

Carskadon, a sleep researcher at Brown University. She says these activities at bedtime

can get kids all excited and make it hard for them to calm down and sleep. Other experts

say part of the problem is chemical. Changing the levels of body chemicals called

hormones not only makes teenagers’ bodies develop adult characteristics, but also

makes it hard for teenagers to fall asleep before 11 p. m.

Because sleepiness is such a problem for teenagers, some school districts have

decided to start high school classes later than they used to. Three years ago, schools in

Edina, Minnesota, changed the start time from 7:25 a. m. to 8:

Students, parents and teachers are pleased with the results.

Snowbirds are people who leave their homes when the temperature drops and head

to warmer climates. They are mostly retirees and business owners who can afford to

take the winter off. While the snow flies in the Northern states, they are enjoying golf,

sailing and barbecues in mild temperatures in the South. Then, after winter passes, they

return to their homes in the North.

Most snowbirds are away from Canada and the Northern states between the middle

of October and the end of November. They pack up and head to Florida, Alabama, Texas,

California, and all of the other Southern states. Some may even go as far as Australia

or Italy to escape the cold winter weather. There are special communities for snowbirds

in many areas. Snowbirds are also offered special discounts in some restaurants, hotels

and area attractions. Several states even have special snowbird resorts（度假胜

地）.There are several online communities and local resources to help snowbirds get

set in their seasonal homes.

Some snowbirds own homes both in the South and in the North. Both homes have

everything they will need for their stay, minimizing the amount of packing necessary

when moving from one to the other. Other snowbirds will rent apartments for the
