If you go into the experimental / really expensive territory I think you can add another 5, maybe 10 years.
So I firmly believe, that today, you can expand your lifespan by 25 years if you do all the right things, you can afford it and of course you don't have very poor genetics.
Where is this estimation coming from ? Out of thin air ?
It's like saying the sky is blue. Obviously extraordinary claims of +10/15 years lifespan require extraordinary evidence.

if you workout (strength + cardio), you eat properly, you minimize stress level and you sleep well 10 years is not only achievable but expected. your life quality will also be day an night in your 70s and beyond (have you ever met someone that is 80 and moves like they’re 50? i have)
most people i’ve talked to are not afraid of being old, they’re afraid of all the health issues and poor quality of life that comes with being old.
so, my question is: if you could have the life quality of a 40yo at 80, and live to 105 instead of 80, would you only consider the improvement to be only 25 years?
