I am EXTREMELY skeptical of epigenetic clocks at the moment, and have been for a few years, but at the same time it's important for these clocks to be investigated and shown to be what they are.

Even though I personally expect them to be readouts of things that don't affect healthspan much, I don't have any more evidence than those trying to work out what they are. I've been wrong before, and also most tech development does not end up living to its promises, but without the investigation we'll never know.

With pharma malfeasance, the penalties are actually big enough, unlike most other fields. Unless you have something particular in mind?
