For some unknown reason, I have agreed to abseil down the side of Lovells' London office building: Atlantic House (see left).

The event, which takes place on 5 September, is to raise money for both The British Paralympic Association and blindness treatment and prevention charity ORBIS.

Not only is it a great cause, but I've never abseiled before and it's a really bloody big building, so please give generously.

Donors are invited to make epitaph suggestions in the comments box.

Donating through Justgiving is quick, easy and totally secure. It’s also the most efficient way to sponsor me: ORBIS gets your money faster and, if you’re a UK taxpayer, Justgiving makes sure 25% in Gift Aid, plus a 3% supplement, are added to your donation.
