As we all set ourselves up for weeks, or even months, of self-isolation, never has there been a better time to think about rules, and the reasons we do the things that we do.

While the UK government has imposed new rules, telling us that we need to stay at home, these rules are only ever an approximation of the ideal rule, which in this case, is the idea that everyone needs to stay at home. The issue here is that while universal isolation is all well and good in theory, we still need health workers and we still need to keep the electricity flowing and the water running.
