We figured there was a lot more life in the idea of people trying to live forever, so all three of our podcast hosts this week - Bronwyn, Katrina and Mark - have picked a topic related to human lifespans. Katrina lets us know how long we can expect people to live, and how both the average life expectancy and upper age limit of living people have changed over time. Mark has been looking into the people who try to use science to extend their lifespan for as long as possible, with some hoping to live forever - although they seem to be trusting more in pseudoscience than evidence-backed treatments. And Bronwyn has compared and contrasted the most well-known cryonics companies, as well as looking into a curious early attempt to bring cryonics to New Zealand.
