The year is 2025, and you turn your mind to the fateful events of five years before: the coronavirus outbreak that entered your consciousness when a place you had never heard of in China went into lockdown. Since then, people you know may have died from Covid-19. Quite possibly, you or loved ones suffered from the virus. Perhaps what stays in your mind are fragments of the news – medical staff in blue hazmat suits, and the daily news briefings from Downing Street or the White House. It could be the Queen in imperial purple saying: ‘We will meet again.’ Things have not been quite normal since.
