Its definitely nice to know (pending, you know, some actual peer-reviewed analysis of this case) that telomere-lengthening treatments are possible in humans, but that&#x27;s only half of a &quot;successful therapy against human aging.&quot;  What are the actual health effects?  We still understand aging so poorly that no single biomarker really represents &quot;biological age,&quot; and certainly there is no scientific consensus on what the root causes are (which may or may not include: telomere degradation, mitochondrial DNA damage, breakdown-resistant protein plaques, weaker epigenetic signalling, and the list goes on.)
