15 December

At an average school Christmas concert or presentation, each person in the room breathes in about 33 litres of used air per hour, breathed out by other people in the room. Imagine somebody giving you mouth-to-mouth and blowing 33 litres of air into you. Wear a mask. I know most won’t, because they have much greater fear of doing something different to what everybody else is doing, than they do of death. That’s how humans work.
