I was very interested in the study reported everywhere in the news today (for example: CNN) regarding how 1 in 4 teen girls has or has had an STD, however every single article was exactly the same leading me to believe they were all simply summarizing a press release. I'd like more info but where should I look for it? (Places I've tried inside) [more inside]

Many years ago someone told me the recognised term for the kind of involuntary shudder that commonly affects people at rest. You know the kind that spontaneously rocks you, just for a moment, like you are shaking off the ghoulies, like the cliche says 'someone was walking on your grave'? I have since lost this word to time, and searching the internet has brought only partial results. Does anyone know it?

So I was perusing Alterslash today and saw a discussion about an article on Technology Review re Immortality research. This is something I myself ask people about and was kind of curious as to what the community response would be.

Leaving aside the actual feasibility of the science, and assuming you could maintain reasonably good health (say frozen at a physical age of 40) would you take Immortality or a hugely extended lifespan (1000+ years) if it were offered to you and why? [more inside]

fff asked a really good question about how children think. Many responders wrote that they have no memories from their childhoods. This freaks me out. I remember my childhood more vividly than my college years. I have a childhood friend who also has no memories from when she was a kid, which is really odd, because I remember all sorts of things we did together. Have there been any studies that shed light over why some people can recall their childhoods and others can't?

What is the lowdown on USANA? A friend of mine swears its great, but seems like a big scam to me... anyone had any experience with this sort of thing? Website is vague and pyramid-scammish.
