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.


Can cocaine make you 'dope sick'?

I have been shooting cocaine steadily for almost two months now and want to know what the difference between the physical and emotional addiction is. I am not sure if I have been experiencing withdrawals, but I feel sick a lot lately. I know shooting heroin has made me sick before. Can cocaine eventually make you dope sick as well?


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?


What's the difference between a vaginal and clitoral orgasm?

What's the difference between a vaginal and clitoral orgasm? Is it only possible to have a vaginal orgasm during intercourse? If you can have a clitoral orgasm through other activity, but not intercourse, why is that? If your clitoris is stimulated during intercourse, will that give you a clitoral orgasm during sex? So how do you have a vaginal one? Can you have both at the same time?


Do diet sodas spike insulin levels?

I have heard that the main reason why diet drinks, like a diet soda, can be bad on a diet, is that it can spike insulin levels and then your body expects sugar that it does not get. I have taken to the habit of only occasionally having diet drinks with meals, so that any increase in insulin is actually met with food in my system. My question is whether or not this is a good/workable strategy, or whether a diet soda is a diet soda no matter when you drink it and is therefore always a bad idea. Thank you for your time.


Why do I experience pain after masturbating at night?

Sometimes I masturbate before I go to sleep at night. Usually nothing is wrong, but sometimes (and this always occurs at night, I've found) after I masturbate, a few minutes later I have to urinate. And when I do, it is usually very painful. The feeling doesn't pass either. My scrotum usually gets very tightened up, and there is painful feeling above my crotch. Usually I just sit there, drink some water until the feeling goes away. ANY idea what this is?


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?
