May 19, 2006: I don't think we will ever need to clone humans because we will have "body 2.0" and organs such as the heart will not be needed, because the blood will use nanotechnology to pump itself through the body. Do you think that body 2.0 will prevail over cloning? Why or why not?

October 11, 2005: I just lost my cat. So, I intend to clone him, one day. So for now I've kept it in the freezer. Thing is, the shock, deciding whether I should bury him or clone him etc took me one and a half hours. So my question is, is there major degradation of the DNA within that time?

March 8, 2005: I am a 53 year old woman who underwent removal of her uterus after two operations for uterine fibroids. I insisted on keeping my ovaries, however, to prevent premature menopause. By now I assume that my eggs are greatly deteriorated and heroic attempts to fertilize them would likely result in an unhealthy fetus. However, is there a way to retrieve healthy DNA from other cells in my body, implant my DNA in the nucleus of a donor egg whose own DNA has been removed, fertilize my egg(s)with my husband's sperm, implant the egg(s)in a donor womb, and obtain a healthy fetus that is genetically like my husband and me?
