    So chronic stress is one of the main contributors to aging. I hope I make it to my 40s.

    Do we currently have the ability to do targeted methylation or de methylation at sites in cells?

      I remember seeing a documentary on that some two decades ago, so we’ve known it for a while. I haven’t watched it since so can’t say if it holds up, but to this day still remember the explanation of telomeres and the story of the baboons.

      It’s been uploaded to YouTube if you’re curious. For future readers, in case the link is dead, it’s called “Stress: Portrait of a Killer”.
