Why can't I stay awake in class?

Lately, I've come to realize that I have a very powerful tendency to fall asleep in class. It seems that I can't stay awake in any lecture style class where I have to listen to the professor and take down notes — where there is minimal engagement on my part. I've pretty much fallen asleep in all of my lecture classes, during one part or another for the whole semester. I think I'm getting regular sleep — six hours at a minimum. I don't like to drink coffee or anything.


Why promote health?

The demographic transformation in our society resulted from better living conditions and improved health status. Why should we promote health when long life spans only create health, economic, and social problems for us?


Will living in New York City make my asthma worse?

I desperately want to attend school in NYC, but have one reservation. I'm asthmatic and I'm afraid that my asthma will be worse in a big city. I traveled to NYC for a week this summer and was fine, but have heard it could be worse in the winter. Can you advise me? I so don't want to let my asthma limit my dream of going to school in NYC.


How do I begin to talk with my children about sex?

I have three young daughters (ages 8, 6, and 3 years), and I know that it is about time to begin teaching them and talking to them about sexual issues. But my mother never talked to me about such things, so I really don't know where to begin. I do need to do it soon, though, because I was molested as a child and I don't want my girls to go through the same thing, you know, thinking they have no one to talk to about such things. Because my Mother never believed me when I told her that someone had molested me, I want my girls to be able to talk to me about anything. But I am very shy and easily embarrassed by certain issues, such as sex. How can I overcome this, and how do I spark a conversation about sex with a six-year-old, what should or shouldn't she know, and how can I explain things so she will understand? Same thing for the three-year-old.


Why do some people gag when someone is vomiting?

Why is it that when a person vomits, it causes others to vomit — even when they don't have an illness causing it? Is this something triggered by the brain or is it something that happens by reflex (survival instinct) for someone to vomit since, perhaps, what the first person was eating may affect the second who vomits as well?


How do I define my sexuality and tell my parents about my transgender partner?

I am a girl, in love with a transgender guy. He was born with the wrong parts, but is truly the kindest person I have ever met. I love him very much, but I am afraid to tell my parents. "Adam" may have been born a female, but he is now a male, and is planing on getting surgery to prove it. My parents are Christians, and I'm not sure they will approve of him. Does me liking Adam, and female to male transgender people, make me a lesbian? Or bi-sexual? My parents deeply disagree with these things and I am afraid to talk to them about Adam.
