got a similar issue with condensation at the moment, this may be of some help!
I had some roof vents tile vents fitted a year or so ago. Still getting condensation / damp starting on some walls.
Even though there are high vents now fitted, it seems that if you don't also have some vents...
I think Bangura's injury may of been caused with him standing on the ball with his right foot and it sliding away. He immediately grabbed the back of his right leg.
