I don't know why I am doing this - I suffer from vertigo but yet have to get out of a 47th floor window! But I am keen to raise money for the Lord Mayor's Appeal in my year as Master of the Worshipful Company of Actuaries so please do support me. I don't think that there is any training to do although I am told that strong core muscles would be useful; I am hoping that gravity will do what is needed to get me down (although I hope to have a system that prevents it from getting out of hand!).
