Well,how arrogant can you get,well knowing you ,probably a lot more.
I am 67,have been using the internet for around 14 yrs,using PC's before that.
Many of my pals exceed even my age,and maybe unbelievably for you,can use the internet.
Notams are available and used by many,especially now there are user friendly sites.
You will always get the odd pratt,usually young,cocky and inexperienced in procedures.
But some of the cocky ones are a lot older

Lister-OAP and proud of it.
