Interesting side note:

Continued failure of the DRE (digital rectal exam) is what ended up getting me booted out of USMC OCS. Apparently in the late 1990's the only people getting screened for prostate issues were Marine Officers.

The Docs had me report the issues to my civilian primary care physicians. He checked my PSA. At 25 it was 2.1. The enlarged / hard prostate and elevated PSA couldn't be brought down before my 26th birthday (the maximum entry age for USMC officers at that time). So I was done.

ETA: I had grown tired of being an architect and had accelerated my survival training ot a point where I felt I needed to "go pro". This led me to Marine OCS. All Marine officers are trained as infantry officers first so I thought it would advance my skill set.
