Last few weeks at the gym I've noticed one young lad evidently having problems with his lower regions. His hands are there more than on the weights so I assume he has some discomfort from an infection, or such like. Would it be unreasonable to discreetly leave the VD clinic phone number on a post it note on his bag, in case he hasn't thought about getting help yet? It's clearly really interfering with his life and not clearing up of its own accord.
