>>> According to him, no supplement has been shown to increase maximum lifespan.
I fully agree with this. Although, really, no testing in this area has been done (on humans), right? So, it's not all that valuable of a statement.
But, we need to be very clear when we talk about extending our healthspans, versus extended our maximum lifespans. Supplements, given the research and indicators we have available, can help us live longer, along with eating well and so on (look at Jack LaLanne). But, our maximum lifespans (~120 years) will not be increased by these methods--we'll only get closer to our maximum. This is still a very good reason to take care of ourselves, because by living closer to our maximum, we are more likely to reach escape velocity.
