First thing I would do, is take my nice fat credit card, and passport, as well as myself, to the airport. There, I would buy a ticket to Spain. I would not eat anything on the plane, since that could seal my fate before I arrive at the destination I'm doing this for. Yeah. Not even peanuts. I don't want to be responsible for taking an entire plane full of people down with me.
That's just bad form.
Upon arrival to Spain, I would begin a week-long fast, so I could see things. When it finally came time to eat, I would probably order all manner of things I'm not supposed to have, then travel to the Picos De Europa, find a good cliff, and Jump.
If I can control the first part, the rest of this might as well be on my terms, too.
