Mind you, I did once know somebody who worked for united parcel Services. They used to send him to all sides of the globe to hand deliver packages, especially medicine which had to be kept in the flight attendants fridge. Stories of flying to south america, coming out of customs, signing the package over to the customer, then turning straight back round and boarding the same aircraft home.

lots of mileage but dont know if i would be putting my degree to much use.
