For that, I needed to think a little bit more like a bat, because rabies is a virus -- it doesn't move by itself, it has to be moved around by its bat host, so I needed to think about how far to fly and how often to fly.
Pour cela, il fallait que je me mette dans la peau d'une chauve-souris, car la rage est un virus – il ne se propage pas tout seul, il se déplace via son hôte : la chauve-souris. Je devais donc réfléchir à  la distance et à la fréquence de vol.
