>As the infant mortality rate was extremely high in the neolithic the average age of the original builders was well below 20

I'm not sure what your trying to say here.

Let's say that 6 siblings are born to one woman and 5 die very soon after birth, with the survivor living on to help build Silbury in his 36th year. The average age of the siblings would be 6 years when the 36 year old was building Silbury. If he died at 60, then the average life expectancy (at birth) of the group woud be 10 years.

A high infant mortality rate, on its own, has no influence on the actual ages of the people who survive infancy.
