Aging is the accumulation of molecular and cellular damage that occurs as an inevitable consequence of metabolic processes required for survival.

“It's the consequence of the accumulation in the body of various molecular and cellular changes that are inevitable consequences of what the body does to keep us alive from one day to the next. Those changes are things that I call damage.”

Aging should be modeled using mathematical equations and physics principles to better understand the process.

“I believe maybe the only answer to your question is that we have to write it in equations.”

Steve Austad believes that Alzheimer's disease will likely be found to have an autoimmune component given the higher incidence in women.

“it makes me actually my private hypothesis that i don't think i've ever said publicly before is i think alzheimer's disease is going to turn out to have an autoimmune component because that's the kind of thing that women seem to be more prone to than men is some of the autoimmune diseases”

The Hayflick limit in cell culture does not accurately reflect or explain the biological process of aging.

“The phenomenon that hayflick more or less discovered was that if you take normal human cells which are not cancer cells and you let them grow in tissue culture they're divide but only a limited number of times about 50 times and then they stop and if you listen to hay flick he then decided that was ”
