Yes, but these are two rather important and complex issues.
The move to telework, I think, accelerates our plans. We had been moving to work zones in which unassigned seating was more of the norm, to recognize that people weren't always in the office. I think the COVID experience has convinced us that we're on the right track, but we certainly need to make some adjustments to how we arrange office space in the future to allow for more telework.
On your second question, around ventilation, I would say that for our buildings, we will follow the guidance of public health and safety. If the health advice requires us to change ventilation, we will, but as far as I know, at the moment we comply with all health and safety regulations.
