Michelle Abadie and Mike Cast are currently working on a new book entitled '8000 Years of Wisdom', a compilation of the memories and anecdotes from 100 octogenarians. A percentage of the royalties will go the Royal Hospital Chelsea's appeal fund.

They have sought out octogenarians from all walks of life, both within the UK and from overseas, who are willing to share their memories and wisdom in this lasting way. Contributors are also being asked for their thoughts on advice for today's younger generation. 

The book is due for publication in November 2009, published by Harper Perennial, an imprint of Harper Collins.
