In this episode I talk to two guests about the risks of alcohol use and attempts to communicate these via the UK's recommended guidelines of 14 units a week. Firstly I talk to Tom Chivers,  science editor at UnHerd and author. We talk about how the risks of alcohol use can or should be evaluated and communicated. Tom recently co-authored a book How to read numbers which includes a Statistical Style Guide  for journalists. Next I speak to Colin Angus,  a Senior Research Fellow in the Sheffield Alcohol Research Group within ScHARR. We talk about the science and development of the UK’s 14 units a week recommended guidelines.
