Dear Sir,
First of all let me congratulate you and the editorial team for producing interesting newsletters. Their regular appearance is comforting to those of us who have had a brush with the problem.
It occurred to me that it may not be common knowledge that the average PSA rises with age. It might help if you could publish a chart showing the average PSA levels of a healthy male over the years say from 50 to 90{!}. This might allay some fears and would give a benchmark, albeit very approximate.

The expert consensus seems to be:
40 to 49 less than 2·5 ng/ml
50 to 59 less than 3·5 ng/ml
60 to 69 less than 4·5 ng/ml
over 70 less than 6·5 ng/ml
