I visited someones workplace this week, she was showing me round the lab which is in the basement of the university. Not being scientific it was all very technical to me of the dozens of microscopes.
I needed some fresh air, because the basement had no windows and what windows there were couldnt open till the 3rd floor but seem to have caught a bug from the A/C or the train on the way home. I am still recovering. Have I breathed in some asbestos?
Another is a christian school thats opening up this year looks like a bomb site at the moment. Of course if you renovating you have nowhere else to go while thats being done and children are learning in amongst the rubble.
