   As an anaesthetist I spend a good amount of time talking, in close proximity, to vulnerable patients while having young children at home coughing and unwell.
   I owe it to my patients not to pass on whatever is circulating at home to them.
   I've been doing it daily for 3 years and can do it as needed for the remainder of my career.

   PS Don’t vape, kids. This is propylene glycol only and only for demonstration purposes
