Another thread got me thinking about this. I open post maybe once or twice a month. I have a letter rack in the hall and just chuck it in there when it arrives. Then just sit down at some point and check through it all at once.
Obviously if I'm waiting for something important like let's say a job offer, I would keep a more careful eye on it but otherwise not.
I'm in my 50s and I'd say I haven't missed anything important in at least 20 years so I don't see a reason to change it but just wondered if I'm unusual in that.
