> One of the things I thought was amazing is that if you solve cancer, you’d add about three years to people’s average life expectancy ... it’s not as big an advance as you might think.
Thinking about improving total life expectancy in this way is not so useful because the large gains have already been made. For instance if no-one in the UK ever died between birth and age 60 it would only add 2-5 years to life expectancy at birth. 100 years ago the same situation would have added 20-25 years.
Perhaps more interesting would be to look at increasing the maximum life span, reducing the variance about the age of death, increasing the median age of death, or to consider the effect of curing cancer/other diseases on healthy life expectancy which I think could still be meaningfully increased.
