I JUST WORKED OUT WHY STANSTED THOUGHT MY HANDS WERE COVERED WITH EXPLOSIVES.

I MOISTURISE THEM WITH SUBSTANTIAL QUANTITIES OF E45 AT LEAST TWICE A DAY.

This happened in January!!! I am a bit .......... at myself for having only just worked it out. (My previous best guess was "I put perfume on my wrists that morning and I guess that's volatile organic compounds????")
