Let's talk about what it means to demystify sex in the elderly. This is not something that gets a lot of attention. David, is it okay for elderly people to have sex?
DAVID KAUFMAN, MD: By all means. I think an important point to make just has to do with an anthropological approach to sex. If we go back in history and we look at other societies, we know that in ancient Egypt, there are hieroglyphics galore, which dealt with sex and sexual positions and sexual issues and sexual problems. The Greeks and the Romans, it's obvious sex was a big part of their society. It's really only our society today, until recently, that sex has been mystified and not spoken about. And it's really only within the last few years that sex is something that is coming on to the open market, that we have television advertisements talking about celebrities who are having sexual problems. So I think we've come a long way in the last few years, and that allows us to have webcasts such as this, which can really help demystify sex for everybody.
MARK POCHAPIN, MD: Pat, are there any benefits in particular that having sex, as someone gets older, that can be seen? Or is it something that you have to worry about with your health?
