Please be advised.
Several posts here mention the involvement with the urine and faeces of other people, even to the extent of these being on or in the face/mouth.
This is bordering on dangerous practice, and probably is dangerous practice, which the Administrator and Moderators frown upon.
For the time being such posts are being left, if only as an illustrations of what is a dangerous practice. However, if anyone else posts on the same or a similar theme, all references will be deleted and probably action taken against members concerned.
