Regarding Dandrews decision to implement a 5 KM movement limit during the recent Melbourne Lockdowns;
- At the end of the day, the line had to be drawn somewhere, with the intent to limit movement of potential spreaders of coronavirus so no matter what number was chosen some destinations would have fallen on the wrong side of the magic line.
I assume 5 KM was chosen as the magic number because, on one hand it allows both sufficient excercise distance for housebound adults to burn off their pent up energy and for most households to be within travelling distance of a major shopping centre where they can purchase essential supplies, on the other hand it prevents potentially virus spreading people from travelling to too many faraway places for non essential reasons such as joyriding around the suburbs on the trains taking photos.
- Another example is the drinking age being set at 18 and not 15 or 21.
I am sure there are some very mature 15 year olds who could handle a nice cold can of beer while relaxing after a long hard day helping their old man at work, just as i am also sure that there are some very inmature 21 year olds who cant handle a few drinks out on the town because they turn into violent animals with no hope of rational thinking whatsoever, but again for the sake of administrative simplicity a line needs to be drawn here too and for the vast majority of people, when weiging up all of the costs and benefits, 18 is a logical legal age for drinking.
