Do cosmetics containing sunscreen provide adequate sun protection?

I was thinking of buying a face powder that says it has an spf of 30. It seems convenient to have a powder sunblock since lotions make my oily face greasy. However, I was wondering if this powder will even be effective as a sunblock since I heard that some moisturizers and other products that advertise an added SPF sometimes don't have a high enough concentration of sunblocking ingredients to make it effective. I would like to know what do you think before I make my purchase.


When are colds contagious?

When is a person with a cold contagious? A couple of friends, who are put off when I keep my distance from their sneezing and coughing, insist one is only contagious a week or so before symptoms appear. In the back of my memory is the idea that one remains contagious until a few days *after* primary symptoms disappear. I'm not usually so concerned about this, but I'm coping with a couple of other annoying health problems and want to try to avoid adding a cold or flu, to boot. I do the usual things news shows recommend — eat well, wash hands frequently. But when should one avoid others who have colds, or when should one stay isolated at home when one has a cold (or flu)?


Why do my bowel movements stink so much?

I am living in a residence hall, and I never realized this until now, but my bowel movements are really smelly. It has gotten to a point where if I don't find a place to do it secretly, it becomes a great source of embarrassment. Could I be eating something that causes my bowel movements to be really smelly?


Why did my father abandon me?

My father left my mother before I was born. They had a good relationship and were happy, but then my mom became pregnant with me. She had trouble telling my father, who was only eighteen at the time, and said she didn't expect him to play a role in my life. So, he left.

I've never seen him or spoken to him in my life. I have no idea what he looks like or who he is and he seems to have no desire to have anything at all to do with me. In fact, he ditched town the day after he found out. I'm mad... I'm mad at my mother for making it so easy for him to leave and I hate that man for what he did. I'm still young and even I can't imagine deserting a child and leaving them without a parent for their entire life. But then maybe that's because I know how it feels and I would never put anyone through that kind of pain. As a girl, I suppose it's hard to understand. Perhaps you can help me to understand his reasoning?


Is there a cure for inverted nipples?

1) I am a male with inverted nipples.

I was wondering if there is any way without surgery to make them come out. They do sometimes come out when it's cold, but go straight back in. I am not overweight, but I do no sports. Would physical activities help???

2) I have inverted nipples. Is there anything that I can do to make them come out? I think that they are unattractive inverted. I have tried massaging them daily as doctors and magazines have suggested, but they do not stay out. They have only come out a couple of times when my boyfriend has sucked on them. Is there something wrong with them? One doctor said that I might have to get a minor surgical procedure.


Does fear of another sex impact my sexuality?

I am a woman who has always been attracted to other women. Until recently, I was attracted to men as well. Now I am almost exclusively attracted to women... which would be fine, except that I think this attraction has a lot to do with painful experiences I’ve had with men. When I was younger, my father was dominant and somewhat abusive, and my first boyfriend was emotionally manipulative and pressured me to have sex with him. After breaking things off with him, I had a very positive sexual relationship with a woman. Am I a lesbian, or am I a bisexual who is just afraid of men? If the latter is true, is there any way to get over this fear?


Can I treat depression on my own?

I'm a first year college student. Since the holidays I started experiencing a very strong horrible feeling; so horrible I preferred to die than to keep on feeling it (the suicidal thoughts come and go still, but it's not as strong as in the beginning). It's very puzzling though because I don't have a reason to feel like this, not one that I know of at least.

I thought of going to a psychologist, or psychiatrist, but I don't have money to do so, and I thought that maybe I should try curing myself first. Is there any way to try to fight depression by myself? Also, if I don't have a reason to feel depressed, what reasons could there be for what's happening to me? I read in other things you wrote to people that depression may be also caused by chemical imbalances in the brain. How do I know if that's happening to me?
