Oh yes. I completely agree on the 'getting caught' threads being pointless and purely negative.
Newbies tend to dwell on them and despite the good & positive issues raised in those threads, all they want to hear are the stories that reaffirm their worst fears.

I was interested in this thread because of the science involved and as I said, the unlikelihood of it impacting upon my life.
Likewise, I doubt I'll ever be playing any kind of contact sport at an international level, in a public arena watched by millions, so the Dougie video doesn't represent an immediate threat or possibility to me at the moment!
It does however, confirm why I wouldn't broadcast my wearing to just anyone.
