We can certainly refer to a number of studies.
David, you may know a little bit more about that.
There are a number of studies—some that originate in Finland and others that are in Japan—that speak to a phenomenon called biophilia where we, as human beings, actually have positive responses to natural materials. It lowers our stress levels.
There is a study that I've heard of—I don't know the source; perhaps you can find it. It was done by the Department of Defense in the U.S. This is a very interesting study because they were looking at stress reduction specifically in the military personnel, which is a huge issue. They were looking at mass timber and natural materials in your everyday environment and how it actually helps to reduce levels of stress in your daily occupancy.
These are studies that perhaps I can help to source. Definitely there are studies out there that speak to wellness, which actually contribute to that.
