We appreciate all the innovation that's moving forward.
You were talking about using wood rather than steel for buildings, but there are concerns, as you know, with fire. There are safeguards when it comes to houses, but certainly when we meet the representatives of the fire department, they continue to be more and more concerned about the use of wood and about fire.
Can you tell me with regard to using it for buildings, and you said for the tallest buildings and for industry, are you able to do anything in particular to safeguard against fire?
