The 3D is funded under the framework of the Call for Proposals VP/2006/018 “ENEA preparatory action on active ageing and mobility of elderly people” .The Coordinator of the project 3D – “Three dimensions” is the Municipality of Thessaloniki – D.E.E.K.M.E. This project aims at preparing older people, and more specifically 55 – plussers, for an active third age. It focuses on three dimensions: activity, volunteerism and mobility. The target group of this project, the so-called baby boomers, is the largest, healthiest, best educated generation in history and they can leave an incredible legacy through service to others in their personal and professional environment. Besides they have gained great experience in life, have more leisure time and also possess sufficient money for mobility purposes; characteristics that qualify them to perform well as volunteers.
