pension age? (Brussels)

what is is the minimum pension age for Belgium?And as ive got pension credits from 2 other european countries would or could this be added to any Belgian credits if i were to live and work in Belgium in the future as i would really like to do also i hear the Belgian health system is supposed to be 1 of the best in the world? currently i live in Ireland and for me i will have to work till im 68 and only recieve my pension after my 69th birthday. At present im 44 and would like to check out my options if i chose to work in Belgium in the not too distant future. I would really like to hear from anybody who knows about Belgian pensions and also health care for the future. thanks for any advice. Davy.
