You can find many fossils inside the Pierre's, which are grassy hard land formations. One hundred million years ago the area was covered by a shallow sea. It was full of prehistoric creatures. When they died their bones collected in the sediment. These fossils are all over the place in the Badlands.
College students, like Americans overall, are sleeping less, and if you are like most college students, chances are you are not getting enough sleep. On average, most college students get 6 - 6.9 hours of sleep per night, and the college years are notoriously sleep-deprived due to an overload of activities. Recent research on college students and sleep indicates that insufficient sleep impacts our health, our moods, our GPA and our safety. Sleep really matters.
The average participant had a BMI of 30, and was 48 years old. The researchers found that total sleep time decreased as BMI increased, except in the severely obese group. Men slept an average of 27 minutes less than women, and overweight and obese patients slept less than patients with normal BMIs. The difference in total sleep time between patients with a normal BMI and the other patients was 16 minutes per day, reaching 112 minutes, or 1.86 hours, over a week.
