<p>D-day is 11th June 2011.</p> <p>&nbsp;</p> <p>In the face of rationality I shall be throwing myself out of a plane from a great height with a man strapped to my back and a large version of one of those Tesco 'Bags for Life' attached to his. I'm hoping there'll also be a second safety one just in case there's a hole in the first, as happened to me in&nbsp;Tesco Bishopsgate aisle 3&nbsp;a few days ago.</p> <p>&nbsp;</p> <p>I've wanted to do this for a while and have finally&nbsp;found a decent price and a worthy cause. All money goes to Engineers Without Borders UK, who do some amazing development work all over the world. Just to confirm, I've already paid for the jump and any sponsorship money will go straight to the good stuff. My employer will also match the amount I raise so it's probably the most cost-effective bout of philanthropy you could ever do.</p> <p>Thanks!</p> <p>&nbsp;</p>
