Thanks S,
prior to posting I did search the forum for "full age" as per the query but the first few of the subsequent hundreds of hits seemed to be "only" finding the individual words "full" or "age", sometimes even within longer words such as "carefully" etc. Please, is there a cunning manner by which I can search the forum more accurately/specifically ?
Cheers J.

ANSWER !

Fear not S, to my great satisfaction I've answered my own question.
just enter "full age" including using the speechmarks and the search engine only finds that exact phrase, excellent stuff.
