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.


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?


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.


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?


How can I take care of my nails if I’m a chronic nail biter?

I am curious as to whether the nail bed regenerates or not. I used to bite my nails, and slowly I've bitten off some of the nail bed as well, on all ten fingers. It has been two years, and the nail bed does not seem to grow back, and my nails grow according to the new shape of the nail bed. It makes my hands look somewhat ugly, to be honest.

Any suggestions would be appreciated.


What are the symptoms of a heart attack?

1) I've heard that the symptoms for heart attack differ for men and women. Could you please send me info on these differences? Also could you give me some possible diagnosis for a feeling of heaviness in the chest?

2) Is it possible to have a heart attack without knowing you're having a heart attack?
