i have no idea what your question means, but i'm presuming owing to the category its about "benefits" as in money rewards paid by the government? Do you get them just for being 50? .....no
if you could be bothered to frame a proper question, i might be bothered to give you an answer that makes sense!
Some insurance policies are cheaper RIAS for one company
Saga Holidays etc for 50s and over
Over 50s clubs in some areas
More wrinkles and aches and pains!
