Why do people find fatty or sugary foods comforting?

Why do people find fatty or sugary foods comforting? I mean, what is it in these types of foods that causes the body / mind to see this type of food as comforting or pleasurable? Surely from the point of view of the body, it prefers foods that are high in nutrients — so why do people who turn to food for comfort always turn to fatty or sugary foods that don't offer the body anything? just wondering??? and I hope that made sense because I'm sorry it's quite badly worded!


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.


Is smoking stunting my growth?

I was wondering if the rumor that smoking cigarettes stunts your growth is true? I am a smoker (not proud) but I do believe it may have stunted my growth or at least slowed it down. And if it does, is it permanent? Like, if I stop smoking, will my growth continue to do what it was originally going to do? Any information is helpful. Thank you I love this site.


How many friends should you have as an adult?

At around 25-30 years old, how many close friends would you need to have in order to live a healthy and happy life? Currently I have 4 reliable people I can depend on. I lost a few close friends along the way, I had 6 in total, should I try to get them back somehow, or just make new ones?
