AUBREY: His analysis presentations it is imaginable to decelerate growing old in mice. Now he desires to check tactics in other people. So I determined to roll up my sleeve for science.

(SOUNDBITE OF PACKAGE OPENING)

UNIDENTIFIED PERSON #1: OK. Slight pinch, needle arising.

AUBREY: All righty.

UNIDENTIFIED PERSON #1: Achieved.

AUBREY: Over the following 4 hours, I used to be poked and prodded, put thru a battery of checks to measure a number of various markers of growing old, together with a scan of my eye.

UNIDENTIFIED PERSON #2: OK. Now we are shifting over to the left eye.

UNIDENTIFIED PERSON #2: Check out to not blink.

VAUGHAN: We are going to simply take an image of the background of your eye, of your retina, after which that’ll be analyzed the use of AI. And it is going to search for adjustments within the retina itself and within the vessels in there as neatly.

Dr. John Wilkins evaluates.

JOHN WILKINS: She walks relatively swiftly, and he or she does not appear to be slowing down, so she has just right staying power.

AUBREY: The lab does these kinds of measurements, together with a DNA research, to assist evaluation my organic age. Thankfully, it got here again more youthful than my exact age. However there have been some surprises. I wish to paintings on construction energy. And a few checks recommend it can be useful to scale back tension.

VAUGHAN: We’ve got the equipment now in an effort to solution that query, does tension pressure an acceleration for your organic age?
