I will be very interesting to see what theses companies claim they expect to achieve in terms of the maximum human life span, instead of the mean. I for one don't think that we have made very much progress at all in that area, and I would be very (pleasantly) surprised if I lived to see anyone reach the age of say, 150 in my lifetime. On the other hand her prediction of being able to extend many peoples life span from say 80 to 100 doesn't strike me as too far fetched because it's basically moving the mean life span up, but not really moving the maximum up.
