In England and America people tend to graze all day long but I think it's such a waste to be constantly picking at food because you then can't enjoy a proper full meal when the time comes.
In my business if I get too close to you and you die it hurts me. And so you develop a natural inclination not to be close to the patient so that if things don't work out ideally you can still get up the next day and care for the next patient.
