I think the key here is understanding how telomeres work. They naturally shorten with age, but the idea that a 90-day hyperbaric protocol could reverse that by 20 years is a stretch. Telomere length is influenced by a complex mix of genetics, lifestyle, and environmental factors. A single intervention, no matter how promising, isn't likely to have such a dramatic effect. Plus, the quote sounds like it's from a non-scientific source—no specifics on the study, no peer review. That’s a red flag. If it were real, it would be everywhere.
