longer life

Researchers are looking for ways to extend our healthy life spans. I know I would like to have more time to do such things as music. However, how will we support ourselves? It's easy to say we can change careers, but will employers hire a 60-year old with a new degree, but no experience in the new field? If we have to spend 100 years working and going to school, with little time for what we want to do, what's the use of that?

Gregory Stock, director of the Program on Medicine, Technology and Society at UCLA’s School of Public Health, says a doubled lifespan would "give us a chance to recover from our mistakes, lead us toward longer-term thinking...".
Since people are so resisting to changing opinions once they are formed, I'm afraid I am not that optimistic.
