Our DNA is not our destiny. - David A. Sinclair

We'd die quite quickly without amino acids, the organic compounds that serve as the building blocks for every protein in the human body. Without them — and in particular the nine essential amino acids that our bodies cannot make on their own — our cells can't assemble the life-giving enzymes needed for life.

How does the SIR2 gene actually turn off genes? SIR2 codes for a specialized protein called a histone deacetylase, or HDAC, that enzymatically cleaves the acetyl chemical tags from histones, which, as you'll recall, causes the DNA to bundle up, preventing it from being transcribed into RNA.

I believe that aging is a disease. I believe it is treatable. I believe we can treat it within our lifetimes. And in doing so, I believe, everything we know about human health will be fundamentally changed.
