Wear a mask indoors. It keeps us safe. 

As an intensive care doctor dealing with some of the worst of the COVID-19 pandemic I am massively in favour of anything that might keep us all safe. I have therefore been upset at the misinformation going out around oxygen levels and masks, as well as confused messaging on when to wear them (indoors!) 

In another life (2019!) I was a triathlete and the pandemic has robbed me of much of my fitness. So to kill two birds with one stone I will run to and from work wearing a mask, and with an oxygen sats meter. I'll post photos (Twitter and Instagram, @LawtonTri). It's 8 miles each way, and if it's nice weather I'll make one of them a half marathon. In between runs, I will be looking after patients (some with COVID-19) and wearing a mask. If I can run 16-21 miles masked, you can probably make it round the shops.

Clearly this will entirely solve everything and put an end to debate on this issue. 

I'm doing this in aid of the Trussell Trust, who operate food banks in Bradford and around the country - and have seen a massive increase in demand due to this horrendous virus.
