My wife doesn't eat crunchy cereal in the morning because it takes too long to eat. She has a point. I'm eating a bowl now and I've been at it for at least 10 minutes.
When you give yourself a short time period to get ready for work and breakfast takes this long you have to multi-task. I've tried shaving and eating cereal at the same time but that doesn't work. You end up with your spoon on your chin and the razor in your mouth. If it wasn't one of the first things you were doing in the morning you might be able to co-ordinate it.
So breakfast will have to be over the keyboard while it's crunchy.
