Do you have any suggestions for trying to stay healthy and sane while working the graveyard shift?

Thanks very much.

I am African-American, but my skin is not that dark. I was never told that I needed sunscreen and when I worked in a daycare I was told in a very delicate manner that only the paler children needed sunscreen. I've been out in the sun for extended periods of time and was wondering if sunscreen is necessary for someone of my complexion. If so, what strength?

What are the reasons for getting white hair in teenagers?

1) This is sort of an embarrassing question...Recently I found out that there is something unusual just outside of my anus. It has grown like a pea. When I touch it, it is sort of hard but smooth, and it hurts a bit. What should I do? Is this like some kind of cancer?

2) I have this problem and I am too embarrassed to ask a doctor about it. I am a nineteen-year-old male and have this growth in my anus. It popped up about one week ago. It is about the size of a pea. Could it be hemorrhoids? If not, what can it be? Should I be worried, and what should I do about it?
