Why we quote Levine
She built one of the most widely used epigenetic clocks, and is among the most direct public critics of what consumer versions of her own method can and cannot tell you.
Morgan Levine, PhD is one of the researchers quoted here; the others quoted alongside Morgan are listed with the same disclosures.
Where they stand, and who pays
Works in industry, and her most-quoted lines on this site argue against over-reading the tests her field produces.
Stating this next to the quote rather than at the bottom of a disclosures page is the whole point. A concession made against a commercial interest is stronger evidence than a neutral summary; a claim made in line with one is weaker. You cannot weigh either without knowing which you are reading.
Everything we quote them saying
The one line, verbatim, in the order they appear in the site's citation index. Each one links to the recording and to the page it is used on.
You can split the same sample, run it twice, and get upwards of eight years difference in your epigenetic age.
