This comment assumes that improvements in longevity will come by themselves with no quality of life improvements. There were plenty of people in their 60s and 70s riddled with cancer and decrepit old bodies from back breaking labor before our lifetimes that probably were waiting for death too. Now that's the age of retirement and a time to explore hobbies and the world for large portions of the population. Personally the one thing I fear is that it will be discovered that it's possible to pause/slow aging but not effectively reverse it. If you start taking the aging pills in your 20s maybe you look and feel 50 when you're 100 but if you start the pills when you're fifty maybe you're feeling like a current 100 year old by your 150th birthday.
