About time! I hope it is something which resolved once the lung healed... I have my best friend fell off the roof working with wires... his lung was punctured, beside other issues... when shit like this happened in your life you pray you do all the research you can do and hope you find something in a doctor would which creates medical miracle.... preserving someone life and maintaining capability! That is a wonderful field to work on and to know it is needed! (my friend are getting better)
