Right. So we can live to 120 or more.
What are we going to do with the time?
How will society adopt?
The tyrrany of the old??
Will we live healthily? What about dementia, which claims at least 25% of people over 70. What % of people over 100 will have dementia, in an age where life expectancy is 120?
What if life extension is only for the rich?

Prospect of human life extension-- Michael West
He discusses technologies which will enable us to extend human lifespan.
We don't know how long our kids will live. Technology currently working in the lab should extend their lifespans to 120 or so, but in another 50 years, the tech could easily be good enough to extend lifespan to 500 or so.
Attainable lifespan is growing faster than 1 year/year, meaning with each passing year, we gain more than one year of extra life.

Ageing: Forever young?
Ageing: Forever young?
When a cell ages, it damages its neighbors. So if you kill all the 'old' cells, you reduce this damage and, while you do not extend lifetimes, you do keep fitness until the end of your days, at least if you are a special lab mouse in a particular experiment.
Old cells are those which have reached the Hayflick limit (the upper bound on the number of times a cell can multiply, and is about 60 times in humans).
Rats, can't find my earlier post discussing that mortality is foundational to morality and spirituality. Social obligations and fear of death.
