R help - Feb 2009 - How do i compute predicted failure time from a cox model?

Given a cox model:

 

library(Hmisc); library(survival); (library(Design); 

cox.model=cph(Surv(futime,  fustat) ~ age, data=ovarian, surv=T)

str(cox.model)

 

What I need is the total estimated time until failure (death), not the
probability of failing at a given time (survival probability), or hazard
etc, which is what I get from survest and predict for example.

 

I suspect the answer is embarrassing simple...
