They say that kids have a different perspective on time. Rewards (or punishments) have to appear in close connection to whatever has been done or the kid won't be able to associate cause with effect.
But what about the rest of us?
Many of us lead a destructive lifestyle. We eat too much, exercise too little and some of us insist on smoking as well. Why? Well, the negative effects aren't immediately apparent.
Some of us ignore safety while driving. Speeds are too high, margin between vehicles too short. Generosity is not the first word that comes to mind on the E4 motorway. Why is this? Well, in all likelihood the risky driver won't directly cause a crash on this particular day. So, he seems to think, let's worry about tomorrow when that day comes.
As a society, we know pretty well by now that our lifestyle is not sustainable. In a matter of a generation or two we're in for pretty drastic changes. Now, will any politician talk straight about climate change in next year's general election? About not flying unless necessary. About choosing local produce at the supermarket. About that car of ours. Hardly a vote-winner.
So, how grown-up are we in fact?
