Not exactly revolutionary. I mean, there's been other mice KO experiences
with IGF-1 and growth hormone to yield increases in lifespan. As for this
experiment, the most interesting part is the fact that the mice do not
develop dwarfism. Yet, IMHO, the most impressive and innovative lifespan
extension in mice remains the p66 experiment.
