Scalish, I'm still trying to get used to this site so I probably could have made myself clearer. Earlier in this thread sveral people were posting things like:

"Looking at all those guys, most of them don't look very bright. Talking about the 'general attrition' hypothesis. It's not like it used to be... But looks can be deceiving though. wink"

So I answered them but probably put it in the wrong place.
