A quote today from Paul Theron, a Joburg-based runner and stockbroker reads, “Marcus Aurelius, the last great emperor of Rome’s golden age, said many years ago that, “We all love ourselves more than other people, but care more about their opinion than our own”. Humans are hardwired this way.” This is mentioned because public safety dates back to Roman times, when a wall collapsed in the Circus Maximus, Rome sometime within the reign of Diocletian between 284 and 286 AD, causing 13 000 deaths.
