 Right. This is the last panel session for today's agenda. And the theme for this session is on designing for density. And in this session, I have four speakers, three of them are architects, and one urban planner, and one urban geographer. Each of the speakers will be given 10 minutes to talk, and then we'll have 30 minutes for discussion. In the interest of time, we are running again behind, 10, 15 minutes behind. So without further ado, I would like to start by introducing the session. This session is on designing for density. And speaking of that, you have heard in the morning sessions and also just now on space and density, that it's interesting that we are not debating whether it's desirable to have high density or not. I think it's quite clear to us that what Ricky started at the beginning and also throughout the presentation, that it's not a matter of high density, but it's a matter of how to find a balance. The balance is between the physical environment and also the societal environment, economic and all that. Let me give you a local example that the desirability of having high density, but at the same time trying to bring in what York child talked about earlier this morning, to bring in the theme of high density and health. Remember the SARS episode that took place in Hong Kong in 2003? In fact, it started off by somebody ate some kind of exotic species, and then that species, the animal carries some kind of virus, and then that person came to Hong Kong and stayed in one of the hotels, and they pressed a hotel lift, and then it happened that the lift button spread the virus. And then that wasn't the end of the story, but the proliferation of that disaster actually took place in one of the high density living areas, in one of the private housing estates that's called Armoid Gardens. And what happened is that somebody was cooking or taking a shower in one of the tiny flats, and then somehow because of the light well or the re-entrance, because of the tightness of that space, it was supposedly as a light well for openable windows, for prescribed windows, so that every flat would have penetration of light and ventilation. But somehow because of that tightness, the virus spread from one flat to another. As a result of that, the entire block or several of those blocks were quarantined, and people have evacuated and lived in the quarantine area for quite a few number of weeks. So it's not a matter of whether we, as a city as a whole, whether we should have high density or not. It's a matter of how we balance those qualities, including quality of living. So in this session, we're hearing the four speakers, each one talking about their own experience. First of all, I would like to invite Rainier Degave as a partner of OMA to start with the presentation. Each of the speakers' bibliographies are all in the handout, and I don't want to spend more time on introducing them, so you can please refer to that. So Rainier, please.
