At home I just collect up any old disks, memory sticks, credit cards
and anything else with storage from the family and keep them until I
am burning garden rubbish. Once there is a nice orange- or yellow-

aluminium runs out of the bottom, all I find in the ashes is the odd
bit of steel. I'd like to see the CIA read that lot!
