The spread of COVID19 can be dampened by us praciting safe or social distancing with each other.  But how far is the 1 metre requirement? Can we train ourselves up to know innately what this distance feels like? 
With the Safe Distancing "One-metre Trainer" you can.  Together with a friend, stand at the respective dotted boxes and notice your distance apart. That is One metre.  In no time, you will have no problem identifying that distance on your own.
