"I know that I'm depriving my son of the sleep he desperately needs as a rapidly growing teenager. I also know that by waking him up hours before his natural biological clock tells him he's ready, I'm literally robbing him of his dreams."
This is an example of Pathos because you feel bad that teenagers are being sleep deprived.
This is an example of Ethos. She is asleep researcher, so she has knowledge of the topic she is talking about.
"Every morning I ask myself, "How can I -- knowing what I know and doing what I do for a living -- be doing this to my own son?" You see, I'm a sleep researcher. "
"In another study with over 30,000 high school students, they found that for each hour of lost sleep, there was a 38 percent increase in feeling sad or hopeless, and a 58 percent increase in teen suicide attempts. And if that's not enough, teens who skip out on sleep are at increased risk for a host of physical health problems that plague our country, including obesity, heart disease and diabetes."
This is an example of Logos. Because it is taking about statistics and facts about a sleep deprived teenager.
