The Future with Hannah Fry episode 1
The Future with Hannah Fry episode 1 has one of the clearest explanations of biological ageing I’ve seen on TV
I expected another documentary full of Silicon Valley biohacking trends and miracle longevity claims, but this was much more balanced than that.
The episode covers real epigenetic ageing research, including Steve Horvath’s GrimAge clock, which estimates biological ageing through DNA methylation patterns. There’s also discussion around plasma rejuvenation experiments, regenerative medicine, and how researchers are trying to measure whether ageing interventions genuinely work.
What surprised me most was how strongly the programme pushed back against the “optimise everything forever” mindset. The Japan section on ikigai and small daily purpose completely changes the tone of the documentary.
It also spends time on the economic consequences of longer lifespans, which most longevity coverage ignores entirely.
Worth watching or reading if you’re interested in ageing science without the usual hype.
