Thought you may say that. How is something in medicine proven? It's not with deduction, it's with induction! So nothing in medicine is proven with 100% certainty. What's left is probability! Even as an anonymous nobody, I'm able to point to hints of life extension in humans today, or 100% increase in lifespan of mammals! Or the work being done on various vectors; ranging from the slowing of ageing, via metabolism, to the reversal of ageing! Then there's something like SENS which has enumerated seven types of ageing. If those seven types of ageing are reversed, then ageing will be reversed. I believe those seven categories are yet to be disproved. So your statement hints at the science of philosophy, and what constitutes proof. As I've said above, I say probability!
