As officials gradually ease the UK out of its coronavirus lockdown, social distancing is arguably more important than ever.
The World Health Organization recommends people keep at least one metre (3.2ft) apart to stem the spread of the infection.
Despite this official guidance, UK officials state we should get no closer than two metres (6.5ft) to those we do not live with.
Pub and restaurants owners have warned their businesses will collapse unless more customers are allowed to mingle closer together.
Evidence suggests the further we stand from a coronavirus patient, the lower our risk of infection.
It may not be as simple as it sounds, however, with the force somebody speaks, how heavily they breathe and the humidity of the space you are in all coming into play.
