Editors are more concerned with the first chapters of a book; that's what everyone reads first in the bookstore or in the online sample.

We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.

I used to do my best thinking while staring out airplane windows. The seat-back video system put a stop to that. Now I sit and watch old' Friends' and 'Everybody Loves Raymond' episodes. Walking is good, but here again, technology has interfered. I like to listen to iTunes while I walk home. I guess I don't think anymore.

I don't fear death so much as I fear its prologues: loneliness, decrepitude, pain, debilitation, depression, senility. After a few years of those, I imagine death presents like a holiday at the beach.

To me, death is dark, pain, grief.

I could have had a session of defecography, which is a diagnostic test in which X-rays are taken to assess anatomical problems occurring during the process of defecation. I gave it the briefest of thoughts before recognizing that this is beyond the pale - even for me.

Picking my topics is sort of a process of elimination for me. Most things don't work for me. I like to cover science and unexpected things happening in labs. Also, theoretical research doesn't work for my style. I need scenes and interactions. Then, humor. I'm having the most fun when I can have fun with my work.

Most of the people who are engaged in the subjects that I look into are pretty interesting. Whether its sex researchers or someone who's devoted their career to saliva or somebody who does research with cadavers, there's an inherent fascination in the subject matter of their work.

For the scientists, they're kind of puzzled and pleased that somebody finds their work interesting. It makes it fun for me. I feel like I've sort of turned over a stone that hasn't been turned over.

Because there are now online databases of federally funded research, and these databases are searchable by keyword, sex researchers have to be careful how they title their projects. It's become a simple matter, for those who are so inclined, to find and target researchers whose work they object to on religious grounds.

If ergonomists have their way, future products won't be built for some hypothetical average person but will conform to the biomechanical needs of whatever particular human body happens to come into contact with them.

Ultimately, the problem is that sex is perceived as a personal, intimate thing, not in the realm of science. But that's not true. It's physiology; it's anatomy. It deserves to be studied.
