How do tattoos work?

How do tattoos work? I mean, if human skin cells are always shedding and reproducing themselves, how are the pigments of a tattoo able to stay in the skin for so long?


Can skin become dependent on moisturizers?

Is it possible to become dependent on moisturizers?

I suffer from dry skin and each Winter go through about half a gallon of moisturizer all over my body by Spring time. It's starting to feel like my skin is getting dependent on the moisturizers, meaning that it always feels like I need them, even if it is a humid season. It's like the skin gave up on circulating its own moisture because it is expecting it from moisturizing cream. Is this just my imagination? Or should I back off on the moisturization?


Is the lump behind my knee a cyst?

I have a one half inch lump inside the back of my leg two inches above my knee (there is no visible mark on the skin). It is not painful or bothersome in any way. An acupuncturist thinks it is a cyst. If it is, what kind might it be, what kind of treatment might I get, and how necessary is it?


Are washcloths and other body scrubbers bacteria factories?

My question is about the cleanliness of loofahs and other body scrubbers. Since they usually hang out in the shower where there is constant warmth and moisture, wouldn't they grow bacteria? How often should they (scrubbers) be changed or how do you clean them? The reason I ask is that I am experiencing some hives, and the only thing I can think that is causing it might be the scrubber gloves in my shower.


Where to meet fellow grad students

1) I am 24 and just started a part time Masters' program. My last relationship was two years ago and I find it pretty difficult at my age to meet respectable guys. I enjoy the bar scene with friends, but don't find that it's very easy to meet good people there.

Anyway, do you have any suggestions as to where to meet decent men at my school and in my age group?

2) As an incoming grad student, I have a rather obvious question, which is something troubling lots of people here, I'm sure. Since we rarely have any academic contacts outside our own departments, where on campus are the best places and/or methods to meet women? It is a little too pretentious to just start talking to them out of nowhere....


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.


Is it possible to be afraid of being raped if I’ve never had sex?

Sometimes I think what it would be like to be with a man, romantically. I am a single woman, and have never had any relationships. Sometimes, though, when I am imagining what it could be like, it turns violent on me, in my mind, and I always end up being raped. This makes me apprehensive and scared of ever becoming involved with anyone. I am scared that everyone I meet will do this to me. I think that it wouldn't be too bad to be single for the rest of my life, but I want to be loved, to be held. What do you think?


How do I navigate a friends with benefits relationship?

1) You have so much information and advice for those who want to start, maintain, or end a relationship; but then there are people like me. I have no desire to be in a relationship with anyone. I'm a full time student, I work two jobs, and I like hanging out with my friends and family when I do have spare time. I'm not interested in the feelings, emotions, and time it takes to be in a relationship. Basically, I'll have sex with anyone before I even think about holding their hand. Then afterwards, the guy will usually end up getting his feelings hurt because I don't want to date him. Is there anything strange or unhealthy about this??

2) I have a good guy friend, and we were talking about friends with benefits. We said how sometimes you want the relationship, but then sometimes not. Then we were talking about how if you want just the perks without the ties, then why not with someone you know and trust. I asked him if he was looking at someone in particular, and he said no, and he asked me and I said not really. The dilemma is that I want to go that step with him. I want to become friends with benefits. But I'm afraid that if I talk to him about it, he'll freak out and reject the idea and I'll lose a friend. I don't know if he would really react that way, but I'm just afraid. We both seem to be looking for the same things and I've been feeling like this for a while now... Should I talk to him about it or just forget about it?
