I don’t know if this is a good sign, a sign of inertia, a sign of snobbishness or for that matter means anything at all! The following three things, once upon a time long long ago, were considered luxuries by me as I could not afford them but now they are luxuries I can afford not to have
#1 Visiting cards
#2 Cell Phone
#3 A notebook computer
Believe me the sky does not fall if you are not carrying any / all of the above – BTW I really liked “Asterix and the Falling Sky”
