I thank the member for his question.
I believe your question is about the useful life of a building.
We owned the last building for over 60 years. In the real estate world, the useful life of a building is estimated to be 60 to 80 years.
The one we have just bought is not yet a year old, because it was just renovated, so it is in very good shape for the next 50 or 60 years.
