phil, i guess that's true for england, but not everywhere! in germany age is a very strict qualifier, in switzerland sometimes more, sometimes less so. apparently age can be important in italy. i don't know for other countries.
to answer the original question, i would say Britain is where you need to look. over here, what you describe for Pisa, would be called ageism. it won't be easy to find funding, though. not because of age but because of residency criteria, as phil pointed out.
