The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
DNA methylation is a process where methyl groups are added to DNA, acting like switches that can turn genes off (other epigenetic switches are on-switches, like DNA acetylation). This affects how our cells read and express genes, and as we age, these switches change in predictable ways. Age-associated alterations in the mammalian DNA methylome are well-documented and thought to promote diseases of aging, such as cancer.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
