When will we finally reverse aging — and could you ever get your 25-year-old body back?
Scientists are already experimenting with cellular reprogramming, senolytics, regenerative medicine, organ replacement and drugs such as rapamycin and metformin. But slowing aging is very different from actually reversing biological age.
In this episode of Future Odds, we calculate the probability of real human age reversal by 2035, 2050, 2070 and 2100.
We explore five possible roads to a younger body:
• Lifestyle and longevity interventions
• Metformin, rapamycin and longevity drugs
• Senolytics and removing “zombie cells”
• Partial cellular reprogramming
• Organ replacement and regenerative medicine
And then we ask the question that really matters:
Could you live long enough to benefit from age-reversal technology?
The biggest surprise may be that age reversal isn't completely alien to nature. Some organisms already display extraordinary regeneration and biological rejuvenation.
The question is no longer simply whether humans can slow aging.
It's whether medicine can learn to turn the biological clock backward — while you're still alive to use it.

resveratrol, DNA RNA nucleotides, EGCG. can all help too. 💈
The Hydra and jellyfish are interesting but I would say on my part, I find closer to us animals like the bowhead whale far more interesting. More than 1,000 times more cells, almost no cancer over a multi century lifespan and minimal senescence relative to us. Seems like the jump to human applicability might be quicker in more closely related species
The Trial done by David Sinclair is called ER-100, Trials for this is already started in a controlled area in the eyes, Started at the start of 2026 and trials are going well. ER-100 would however be quite expensive even if one day made full body.
However, Something that is not talked about strangely, Is SL-100. A chemical cocktail that essentially does what ER-100 does with just 3 ingredients. Currently David Sinclair and his team are trying to create one single compound for it.
SL-100 is the thing people should be talking about, Not so much ER-100 (Though ER-100 is equally incredible). But SL-100 is infact entirely or mostly full body rejuvenation, David Sinclair is going to start trials of it by the end of 2026 or early 2027 if things go well. SL-100 will offer the same benefits of ER-100, But in a drinkable liquid or pill form. Significantly cheaper at around 100 dollars to create (This does not factor in things like production, Market value, etc so keep this in mind), Sinclair hopes to have it be apart of the 2030 Xprize competition.
So the chances that we enter LEV is actually remarkably high within just 5-7 years alone.
AI itself is actually doing some mind blowing things in the Medical Science Field. The 3 compounds used in David Sinclair's SL-100 would've normally took 160 years to find, AI managed to do it in 2 months.
I believe the chances we achieve LEV or straight up cellular rejuvenation by 2035 is almost near certain, I'd say at the current rate of things, It's harder NOT to achieve it by 2035, Even better yet, Due to rapidly dropping fertility rates worldwide. It's very likely governments will try to offer it to citizens to prevent population collapses.
