It's Long Now Seminar time again. This month is Dr. Michael West, CEO of Advanced Cell Technology, talking about "the Prospects of Human Life Extension." It's the first of two seminars on the topic; next month is Ken Dychtwald on the "Consequences of Human Life Extension." WorldChanging readers already have a heads-up on some of the issues -- I covered them last month in my essay "What Would Radical Longevity Mean?"

The Michael West talk is this Friday, November 12, at the Fort Mason Conference Center in San Francisco. Doors open at 7pm, lecture begins at 8pm. Admission is free.
