2. I believe all governments should create Warpspeed for this approach. At the depths of covid lockdowns, GDP was down 20%. Imagine the massive GDP creation from making every 65+ year old feel 40 again. They'd work, consume, and generally flourish. Even if it's only 10 more years of quality life, this is the greatest good that could be done for humanity. To avoid another 10 years of my parents death is something I'd do a lot for. Economically and ethically, we should prioritize this research above most else.
3. This approach is scientifically sound. Certain aspects of aging cures are approaching engineering levels of work rather than pure science. We simply know that many diseases are caused or amplified by senescent cells. And we have ample evidence that elimination of these cells reverses diseases in complex mammals, as long as you don't remove too many, too quickly. The rest, is the engineering problem of how to remove the right cells at the right cadence.
4. This is the kind of thing biohackers should hack on. Find an aging part of your skin, and attempt to convince your body to kill the senescent cells. If you succeed, you will have benefited humanity, become beautiful, become wealthy, and be remembered forever (is there any other fundamental need humans have, not covered)?
Let the race begin!
