Safety first

The government was criticised for its new coronavirus slogan, ‘Stay alert’. What are the most common safety slogans in use in workplaces?
— ‘Safety is our number one priority’
— ‘Safety is no accident’
— ‘Take five and stay alive’
— ‘The key to safety is in your hands’
— ‘No safety, know pain’
The word ‘alert’ doesn’t appear until number ten: ‘Stay alert, don’t get hurt’.

Distant future

What would a perfectly socially distanced United Kingdom look like?
— The land area of the UK is 245,000 sq km, or 245 billion sq metres.
— The population is 65 million.
— Therefore, if we all spread out evenly we would have 3,770 sq metres each.
— If you divided Britain into squares of this size there would be approximately 61 metres (200 feet) between us and the next person.
